Military & Aerospace Electronics

As the infantry adapts to

commercial technology, 

questions remain on how best

to use it


THE MIL & AERO COMMENTARY, 29 Sept. 2016. The 
modern-day infantrywarfighter has a big job to do. He and others
 in his rifle squad could find themselves temporarily isolated on
the leading edge of the battlefield with no clear idea where the
 enemy is, how many of them there are, what they look like
, and what kinds of weapons they have. Iscommercial technology 
the answer?
The first warning that they're suddenly in grave danger might be a
 wisp of smoke, a ricocheting bullet, or the pop or a mortar launch
 nearby. In a moment they could be in an ambush -- pinned down
 and surrounded -- with incoming fire from what seems like all directions
.
Under heavy pressure, members of the rifle squad hug the ground, radio for
 help, and desperately look around for signs of the enemy. Squad mates
 start taking hits, yet the squad still isn't certain of how and where to fight 
back. Although help is on the way, it's many minutes out at a moment when
 seconds count.
This kind of scenario is increasingly common for the infantry in an era
 when they typically operate in far-away unfamiliar surroundings in 
which the enemy blends in with the civilian population, has wide access
 to tactical communications systems like cell phones, can sow booby
 traps called improvised explosive devices (IEDs), and has intimate
 knowledge of the local terrain and culture.
In other words the enemy has far superior situational awareness than do
 members of the infantry rifle squad whom they have pinned down and
 in their sights.
At this moment, however, things are not all bad. The rifle squad, for example
, has a technological advantage with a variety of sensors, wearable computers, 
secure radio communications, and superior fire power. Still, technology
 itself may not be the answer, but instead may have to do with using the 
technology that's available.
The U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington,
 Va., is working with Lockheed Martin Corp. to sort out some of today's
 conundrums of how the infantry can use modern technology to best 
advantage in bad circumstances.
This isn't a new issue for U.S. warfighters. One of the military's biggest
 challenges today is to sort out a continuing avalanche of new commercially
 developed technologies, finding those that are most suitable for warfighters
 in the field, and adapting these technologies to the military's chain of command.
Given a commercial cell phone and working cell network today, for example,
 and a private soldier in a foxhole could phone the White House. Despite 
having this capability, however, that's rearely the best idea. The trick is to
 use available technology to enable infantry to fight harder, longer, and smarter.
This is where the DARPA Squad X Core Technologies (SXCT) program comes 
in. It seeks to develop new technologies that give infantry squads of eight to
 14 members increased situational awareness, as well as improved capabilities 
in precision engagement, non-kinetic engagement, squad sensing, and squad
 autonomy to enable these front-line warfighters to adapt to quickly changing
 battlefield conditions.
In particular, the DARPA SXCT program seeks to develop new kinds of
 guided ammunition for current squad equipment like the M203/M320 
grenade launchers or the Picatinny Rail system. One weapon that could emerge 
from this program is a micro-missile or advanced 40-millimeter grenade that 
can engage unseen targets with precision using the networked squad, small 
unmanned vehicles, and data-fusion-enabled shared situational awareness.
Other SXCT thrusts include tactical battlefield cyber, optical, and electronic 
warfare jammers to disrupt enemy communications and weapons control; 
handheld radar, and small sensors that look and listen for enemy sounds 
like heart beats or infrared signatures.
The Lockheed Martin Corp. Missiles and Fire Control segment in Grand 
Prairie, Texas, won an SXCT phase-2 contract this month to start refining
 and enhancing infantry technology concepts developed in the program's first phase.
It's likely to be a while before any SXCT technologies could be deployed in 
the field, and also possible the program won't ever yield any promising 
solutions. Still, this is encouraging news to any infantryman who's ever been
 pinned down in enemy territory.
