Whilst this scores top points in the tech dept, it really fails miserably in the infantryman dept.
The core problem being addressed by this technology is - That your unit is being shot at by an enemy who knows where you are, and you have no clue about their location .. at least until they open fire on you, at a time and place of their choosing.
If your units are consistently in that position, then its already game over long before the first shot is fired.
Adding thousands of dollars worth of electronics to your walking cannon fodder is barely an adequate response. It smacks of desperation far more than it does intelligence.
How about TRAINING your soldiers to patrol properly in the first place ?
It would be far better to know where the enemy is first, keep your own movements hidden, and engage on your own terms. Fancy electronics are not going to help here at all, especially against an enemy who is capable of BASIC good old fashioned fieldcraft.
Thank God I have fellow Australian soldiers covering my ass if I am ever back at the sharp end.
