There was tailk not too long ago about replacing dogtags with tatood barcodes to help identify soldiers in battle. The trouble with tatoos are that they are superficial and can be easily mutilated by battle and human interference.

That brings up the possibility of micrchipping our soldiers. Just like our pets, an identifying serial number is assigned to each chip which would be injected into the body. When scanned, the number shows up making identification easy.

Microchips should not put our soldiers in danger of being electronically outed by technology but you never know how sophisticated new technology can be.
