Blue tooth, 802.11b, 802.11g and all that certainly provide enough of 
this for ideas. The only major problem is that if you're emitting RF, 
you're easier to detect. Your unit has to spend time dropping other 
dummy emitters to compensate and muddy the waters to keep your 
enemy's information value to a minimum. Now, laser based signals or 
something that is very short ranged would help, but lasers need fancy 
controls to keep it all tuned and low power transmitters can still be 
detected with good strong signals.

Though, to be honest, if you're in combat, they probably already know 
you're there. Your greatest problem up to then is keeping your 
signals quiet until you make contact so as to prevent giving your 
positions away. A burst transmit type system would be best, how to 
build that in real world is certainly tricky.
