I can't really agree entirely, firebug, because we have actually seen the exact opposite in the past years.
Part of the reason the current Land Warrior/Future Force Warrior system hasn't been widely implemented is its vulnerability to sabotage. The main design principle behind the current phase of it is separation of critical parts from tactical parts, so that wireless sabotage cannot remove a soldier's ability from the field. In other words, they are designing it intelligently. It's last field tests went extraordinarily well, but we still don't field it in force, despite it's major advantages, because of these few flaws that it has.
The system is designed to keep as much information localized to each soldier as possible, while transferring only what it needs to wirelessly. Keep in mind, it's still not considered viable for anything other than field tests even though it doesn't destroy a soldiers weapons when hacked.
What can the Land Warrior/Future Force Warrior system do:
-Shoot Around Corners
-Target Acquisition
-Thermographic/IR Capability
-Video Feed (Wireless Transmit)
-GPS transmitter/Dead Reckoning Module (essentially and Orientation System)
-Combat Identification to Reduce Friendly Fire (two versions, one scans the video feed to analyze uniforms with no need for wireless information, one reads the GPS transmitter and checks against the scanned video)
-Eye Display for tactical information (maps, troop placement, weapon viewpoint or wireless information from other soldiers with system)
-Health Monitor (Wirelessly transmits health conditions to nearby soldiers and/or officers)
-Subvocal Mic and Eye Tracking Operating System for hands free communication and computer management
That's just what it can do today, and by that, I mean three years ago when the last field test was released (which was probably done a year or more before that. The plans for 2032 literally blow the combat gear in SR out of the water.
The point here is that only a few of the current systems use wireless capabilities, and it's still not considered viable because of it's wireless vulnerabilities. Transmitting video feeds (which can be shut off), soldier location (which can be shut off), one form of Friendly Fire ID (which can be shut off without negating the entire system), a bit of the tac display (most mission information is loaded to start with), and the Health Monitoring (which can be shut off), those by themselves make the system unfeasible because of the information they give the enemy.
In 2007 they almost scrapped the program entirely because they were having issues getting the weight down. They were two pounds over their goal. If two pounds of weight makes them consider scrapping it, I can't imagine what telling them, "you can use this, but it opens up your guns to being destroyed by hackers," would do. That's multitudes worse than their current issues with the system.
It's not that they would never use this system, it's been field tested many times. It's that this system would never go into full production with gaping design flaws like SR has.
Some people say that soldiers wouldn't need the extra edge from a Smartgun, but who exactly is that Smartgun designed for? These are combat systems. They're designed for police forces and soldiers and security teams.
