A Post-Sequestration Blueprint for a Leaner and Smarter Military

Leave a comment

Five months after the much-dreaded sequestration went into effect, many defense analysts and military officials alike are worried about the negative repercussions of the drastic budget cuts on military readiness. In his latest commentary, the rightwing commentator Alan Caruba declared that “The U.S. military is on life support.” Defense Secretary Chuck Hagel also argued in his Statement on Strategic Choices and Management Review (SCMR) that “sequester-level cuts would ‘break’ some parts of the strategy, no matter how the cuts were made [since] our military options and flexibility will be severely constrained.”

To its credit, the SCMR seemed to hint at operational and structural adjustments underway by offering two options—trading “size for high-end capacity” versus trading modernization plans “for a larger force better able to project power.” Nevertheless, one important question which went unasked was whether or not the US Armed Forces alone should continue to play GloboCop.

The current geostrategic environment has become fluid and fraught with uncertainties. As Zhang Yunan avers, China as a “moderate revisionist” will not likely replace the United States as the undisputed global champion due to myriad factors. As for the United States, in the aftermath of a decade-long war on terror and the ongoing recession, we can no longer say with certainty that the United States will still retain its unipolar hegemony in the years or decades to come.

That said, Secretary Hagel is correct that the United States military may need to become leaner in the face of harsh fiscal realities. To this must be added another imperative: The US Armed Forces must fight smarter and must do so in ways that may further America’s strategic and commercial interests abroad.

So how can the United States military fight smarter and leaner?

COCOMs
Possible Combatant Command Realignments

First, given massive troop reductions whereby the Army personnel may be reduced to 380,000 and the Marine Corps “would bottom out at 150,000,” while at the same, the DoD is seriously considering restructuring existing Combatant Commands (COCOMs), it no longer makes sense to deploy or train troops for protracted counterinsurgency campaigns or foreign occupations. Instead, should another transnational terrorist group or a rogue state threaten homeland security, the United States could rely on SOF (Special Operations Forces) commandos and UAV (Unmanned Aerial Vehicles) to selectively target and neutralize potential threats. While the SOF and UAV surgical raids should not be viewed as substitutes for deft diplomacy, they can provide cheaper and selective power projection capabilities.

Second, since the United States Navy may be forced to “reduce the number of carrier strike groups from 11 to 8 or 9,” it can meet its power projection needs by encouraging cooperation among its sister navies and by bolstering their naval might. One example of such partnerships would be to form a combined fleet whereby America’s sister navies “may share their unique resources and cultures to develop flexible responses against future threats” posed by our adversaries.

Third, the United States may encounter more asymmetric threats in the form of cyber attacks, CBRN (Chemical, Biological, Radiation, Nuclear) attacks, and may also be subjected to attacks from within by homegrown terrorists and drug cartels—all of which may wreak havoc and may even cripple America’s domestic infrastructures. As retired Admiral James Stavridis argues, such asymmetric attacks may stem from convergence of the global community. Such threats require that the United States take the fight to its adversaries by cooperating with its allies to “upend threat financing” and by strengthening its cyber capabilities.

Fourth, where rogue states such as Iran, Syria and North Korea, are concerned, the United States could implement what General James Mattis refers to as the “proxy strategy.” Under this arrangement, while “America’s general visibility would decline,” its allies and proxies would police the trouble spots on its behalf.

Fifth, the United States must be prepared to defend homeland against potential missile attacks from afar. The United States may be vulnerable to hostile aggressions from afar following North Korea’s successful testing of its long-range rocket last December and Iran’s improved missile capabilities. Thus, improving its missile defense system will allow greater flexibility in America’s strategic responses both at home and abroad.

Last but not least, the United States Armed Forces needs to produce within its ranks officers who are quick to grasp and adapt to fluid geostrategic environments. One solution, as Thomas E. Ricks proposes, would be to resort to a wholesale firing of incompetent generals and admirals. However, it should be noted that rather than addressing the problem, such dismissals would ultimately breed resentment towards not only the senior brass but civilian overseers, which will no doubt exacerbate civil-military relations that has already soured to a considerable degree. Instead, a better alternative would be reform America’s officer training systems so that they may produce commanders who possess not only professional depth but breadth needed to adapt to fluid tactical, operational, and strategic tempos.

“The US Military Establishment’s Greatest Foes” By Jack Ohman/Tribune Media Services

Despite the hysteric outcries from the service chiefs and many defense analysts, in the end, the sequestration may not be as dire as it sounds. In fact, Gordon Adams argues that after several years of reductions, “the defense budget…creeps upward about half a percentage point every year from FY (Fiscal Year) 2015 to FY 2021.” Simply stated, one way or the other, the US Armed Forces may eventually get what it asks for–as it always has been the case. Nonetheless, the sequestration “ordeal”—if we should call it as such—offers the US military object lessons on frugality and flexibility. Indeed, American generals and admirals would do well to listen to General Mattis who recently admonished them to “stop sucking their thumbs and whining about sequestration, telling the world we’re weak,” and get on with the program.

Leading the Blind: Teaching UCAV to See

3 Comments

In “A Scandal in Bohemia”, Sherlock Holmes laments, “You [Watson] see, but you do not observe. The distinction is clear.” Such is the current lament of America’s fleet of UCAVs, UGV’s, and other assorted U_V’s: they have neither concept nor recognition of the world around them. To pass from remote drones living on the edges of combat to automated systems at the front, drones must cross the Rubicon of recognition.

To See

Still can't see a thing.
Help!

The UCAV is the best place to start, as the skies are the cleanest canvas upon which drones could cast their prying eyes. As with any surveillance system, the best ones are multi-faceted. Humans use their five senses and a good portion of deduction.  Touch is a bit too close for UCAV, smell and hearing would be both useless and uncomfortable at high speed, and taste would be awkward. Without that creative deductive spark, drones will need a bit more than a Mk 1 Eyeball. Along with radar, good examples for how a drone might literally “see” besides a basic radar picture are the likes of the layered optics of the ENVG (Enhanced Night Vision) or the RLS (Artillery Rocket Launch Spotter).

Operators for typical optical systems switch between different modes to understand a picture. A USN Mk38 Mod-2 24MM Bushmaster has a camera system with an Electro-Optical System (EOS), Forward Looking Infrared (FLIR), and a laser range-finder. While a Mod-2 operator switches between the EOS and FLIR, in the ENVG, both modes are combined to create an NVG difficult to blind. For a drone, digital combination isn’t necessary, all inputs can be perceived by a computer at one time. Optical systems can also be put on multiple locations on the UCAV to aid in creating a 3D composite of the contact being viewed. Using an array of both EOS and FLIR systems simultaneously could allow drones to “see” targets in more varied and specific aspect than the human eye.

For the deployment of these sensors, the RLS is a good example of how sensors can “pass” targets to one another. In RLS, after target data is collected amongst audio and IR sensors, flagged threats are passed to the higher-grade FLIR for further designation and potential fire control solution. A UCAV outfitted with multiple camera systems could, in coordination with radar, pass detected targets within a certain parameter “up” to better sensors. Targets viewed in wide-angle scans (such as stealth aircraft only seen) can be passed “down” to radar with further scrutiny based on bearing. UCAV must be given a suite of sensors that would not merely serve a remote human operator, but for the specific utility of the UCAV itself that could take advantage of the broad-access of computer capabilities.

And Observe

In-game models for real-life comparison.
In-game models for real-life comparison.

However, this vast suite of ISR equipment still leaves a UCAV high-and-dry when it comes to target identification. Another officer suggested to me that, “for a computer to identify an air target, it has to have an infinite number of pictures of every angle and possibility.” With 3-D rendered models of desired aircraft, UCAV could have that infinite supply of pictures with varying sets of weapons and angles of light. If a UCAV can identify an aircraft’s course and speed, it would decrease that “range” of comparison to other aircraft or a missiles by orienting that contact’s shape and all comparative models along that true motion axis. Whereas programs like facial recognition software build models from front-on pictures, we have the specifications on most if not all global aircraft. Just as searching the internet for this article, typing “Leading” into the search bar eliminates all returns without the word. In the same way, a UCAV could eliminate all fighter aircraft when looking at a Boeing 747. 3-D modeled comparisons sharpened by target-angle perspective comparisons could identify an airborne contact from any angle.

A UCAV also need not positively identify every single airborne target. A UCAV could be loaded with a set of parameters as well as a database limited to those aircraft of concern in the operating area. AEGIS flags threats by speed, trajectory, and other factors; so too could a UCAV gauge its interest level in a contact based on target angle and speed in relation to the Carrier Strike Group (CSG). Further, loading every conceivable aircraft into an onboard database is as sensible as training a pilot to recognize the make and model of every commercial aircraft on the planet. A scope of parameters for “non-military” could be loaded into a UCAV along with the specific models of regional aircraft-of-interest. The end-around of strapping external weapons to commercial aircraft or using those aircraft as weapons could be defeated by the previously noted course/speed parameters, as well as a database of weapons models.

Breaking Open the Black Box

The musings of an intrigued amateur will not solve these problems; our purpose here is to break open the black box of drone operations and start thinking about our next step. We take for granted the remote connections that allow our unmanned operations abroad, but leave a hideously soft underbelly for our drones to be compromised, destroyed, or surveilled at the slightest resistance. Success isn’t as simple as building the airframe and programming it to fly. For a truly successful UCAV, autonomy must be a central goal. A whole bevy of internal processes must be mastered, in particular the ability of the UCAV to conceive and understand the world around it. The more we parse out the problem, the more ideas we may provide to those who can execute them. I’m often told that, “if they could do this, they would have done it”… but there’s always the first time.

Video Game AI and the Future UCAV Top Gun

My brother in flight school should be glad we played so much Ace Combat 4.
Alright, Roomba, now start sweeping for enemy units.

A Roomba is useful because it can sweep up regular messes without constant intervention, not because it can exit and enter its docking station independently. Although the Navy’s new X-47B Unmanned Combat Air Vehicle (UCAV) has, by landing on a carrier, executed an astounding feat even for humans, this ability only means our weapons have matured past their typical one-way trips. The real challenge will be getting a UCAV to defend units while sweeping up the enemy without remote guidance (i.e. autonomously). The answer is as close as the games running on your Xbox console.

 

 

Player One: Insert Coin

Simulated fighters are UCAVs having an out-of body experience.

Considering the challenge of how an air-to-air UCAV might be programmed, recall that multiple generations of America’s youth have already fought untold legions of advanced UCAV’s. Developers have created artificial “intelligences” designed to combat a human opponent in operational and tactical scenarios with imperfect information; video games have paved the way for unmanned tactical computers.

A loose application of video game intelligence (VGI) would work because VGI is designed to operate in the constrained informational environment in which a real-life UCAV platform would operate. Good (i.e. fun) video game AI exists in the same fog of war constraints as their human opponents; the same radar, visual queues, and alerts are provided to the computer and human players. The tools to lift that veil for computer and human are the same. Often, difficulty levels in video games are not just based on the durability and damage of an enemy, but on the governors installed by programmers on a VGI to make competition fair with a human opponent. This is especially evident in Real Time Strategy (RTS), where the light-speed all-encompassing force management and resource calculations of a VGI can more often than not overwhelm the subtler, but slower, finesse of the human mind within the confines of the game. Those who wonder when humans will go to war using autonomous computers fail to see the virtual test-bed in which we already have, billions of times.

This Ain’t Galaga

No extra lives, and forget about memorizing the level's flight patterns.
No extra lives, and forget about memorizing the level’s flight patterns.

Those uninitiated must understand how VGI has progressed by leaps and bounds from the pre-programmed paths of games such as the early 1980’s arcade shooter Galaga; computer opponents hunt, take cover, maneuver evasively, and change tactics based on opportunities or a sudden states of peril. The 2000’s Half-Life and HALO game series were especially lauded for their revolutions in AI – creating opponents that seemed rational, adapting to a player’s tactics. For the particular case of UCAV air-to-air engagements, since the number of flight combat simulators is innumerable, from Fighter Pilot on the Commodore 64 in 1984 to the Ace Combat series. Computers have been executing pursuit curves, displacement rolls, and defensive spirals against their human opponents since before I was born.

However, despite its utility, VGI is still augmented with many “illusions” of intelligence, mere pre-planned responses (PPR); the real prize is a true problem-solving VGI to drive a UCAV. That requires special programming and far more processing power. In a real UCAV, these VGI would be installed into a suite far more advanced than a single Pentium i7 or an Xbox. To initiate a learning and adapting problem-solving tactical computer, the DARPA SyNAPSE program offers new possibilities, especially when short-term analog reasoning is coordinated with messier evolutionary algorithms. Eventually, as different programs learn and succeed, they can be downloaded and replace the lesser adaptations on other UCAVs.

I’ve Got the Need, The Need For Speed

Unlike Maverick, drones will never have to go through motorcycle safety training.
Unlike Maverick, drones will never have to go through motorcycle safety training.

When pilots assert that they are more intuitive than computer programs, they are right; this is, however, like saying the amateur huntsman with an AR-15 is lesser trained than an Austrian Arabesquer. The advantage is not in the quality of tactical thought, but in the problem solving rate-of-fire and speed of physical action. A VGI executing air-to-air tactics in a UCAV can execute the OODA loop encompassing the whole of inputs much faster than the human mind, where humans may be faster or more intuitive in solving particular, focused problems due to creativity and intuition. Even with the new advanced HUD system in their helmets, a human being cannot integrate input from all sensors at an instant in time (let alone control other drones). Human pilots are also limited in their physical ability to maneuver. G-suits exist because our 4th and 5th generation fighters have abilities far in excess of what the human body is capable. This artificially lowers aircraft tactical performance to prevent the death or severe damage of the pilot inside.

Pinball Wizard: I Can’t See!

VGI doesn’t have a problem with the how, it’s the who that will be the greatest challenge when the lessons of VGI are integrated into a UCAV. In a video-game, the VGI is blessed with instant recognition; its enemy is automatically identified when units are revealed, their typology is provided instantly to both human and VGI. A UCAV unable to differentiate between different radar contacts or identify units via its sensors is at a disadvantage to its human comrades or enemies. Humans still dominate the field of integrating immediate quality analysis with ISR within the skull’s OODA loop. Even during the landing sequence, the UCAV cheated in a way by being fed certain amounts of positional data from the carrier.

We’ve passed the tutorial level of unmanned warfare; we’ve created the unmanned platforms capable of navigating the skies and a vast array of programs designed to drive tactical problems against human opponents. Before we pat ourselves on the back, we need to effectively integrate those capabilities into an independent platform.

Defeating Floating IEDs with USVs

Leave a comment

By CDR Jeremy Thompson, USN

This concept proposal explores a technology solution to the problem of risk to first responders when identifying, neutralizing, and exploiting “surface-floating” maritime improvised explosive devices (SF/MIEDs).

Does the Navy need a maritime equivalent of the Talon Counter-IED robot?
Does the Navy need a maritime equivalent of the Talon Counter-IED robot?

When considering the proliferation of technology for use against land-based improvised explosive devices (IEDs), it may be puzzling to many observers why remote IED Defeat (IEDD) technologies, particularly robots, have yet to fully cross over into the maritime domain. Although some unmanned underwater vehicle programs designed for limpet mine-like object detection on ships are in development, much less attention has been given to countering SF/MIEDs. In general, the purpose of MIEDs is to destroy, incapacitate, harass, divert, or distract targets such as ships, maritime critical infrastructure and key resources (CI/KR), and personnel. MIEDs may also present obstacles (real or perceived) with the purpose of area denial or egress denial. As a subset of the MIED family, the “surface-floating” MIED operates on the water’s surface in environments such as harbors, the littorals, the riparian, and the open ocean. It may be either free floating or self-propelled, with remote control (manual or pre-programmed) or with no control (moves with the current). It is a tempting low-tech, low-cost option for an adversary.

Thankfully, SF/MIED incidents have been rare in recent times, the last significant use occurring during the Vietnam war. Nonetheless, a capability gap is highlighted by the challenge they represent—namely, that a human must unnecessarily expose themselves to the object. One material solution to a surface-floating IED may be to develop an IED Defeat Unmanned Surface Vessel (USV) around a design philosophy based on IEDD robots used in land warfare. Protection of high value units and critical infrastructure / key resources would be its primary missions along with counter-area denial. Its most likely operating environment would be CI/KR dense areas such as harbors and seaports as well as the riparian environment since rivers are constricted in the water space available to shipping to maneuver around SF/MIED threats. A key element of design philosophy in an IEDD USV would be to meet the expectations of the customer—the first responder. Military explosive ordnance disposal (EOD) units and civilian bomb squads are much more likely to accept a platform in which the console and all other human interface features are nearly identical in look, placement, feel, and responsiveness as the most popular robots they have been accustomed to operating such as the TALON robot by QinetiQ and Packbot by iRobot.

A functional hierarchy could be drawn around major tasks such as reacquisition of a suspected surface-floating IED, identify/classify, threat removal, neutralization, and recovery of the IED for exploitation. Modularized payload packages to execute these tasks may include a towing package, an attachments package (e.g. hooks, magnets), a neutralization tool package to include both precision and general disruption EOD tools, an explosives, chemical, and radiological detection package, and an electronic counter-measures package.

Numerous trade-offs between weight, power, stability, and the complexity of modular packages would need to be considered and tested, however, variants like a “high-low” combination of a complex and simple USV working together may minimize some of the trade-off risk. If an IEDD USV were to be developed key recommendations include:

  • Official liaison between NAVSEA (US Naval Sea Systems Command) between PMS-406 (Unmanned Maritime Systems) and PMS-408 (EOD/CREW program) to ensure the transfer of USV expertise between PMS divisions.
  • A DOTMLPF assessment to determine whether limpet mines or surface-floating IEDs are more likely and more dangerous to U.S. assets and personnel given the uncertainty of future naval operations.
  • Including civilian bomb squads in the design and development process early to increase the potential for demand and cross-over with the law enforcement sector and therefore reduced long-term program costs.

Current UUV programs under development include the Hull UUV Localization System (HULS) and Hovering Autonomous Underwater Vehicle (HAUV).
