The oldest biometric is your appearance, which is pretty unique. Next came fingerprints, which were first recognized as a biometric indicator four centuries ago, but did not become a feature of police work until 150 years ago. That was followed by blood types and a whole bunch of stuff you could only do with dead bodies. But in the past few decades, there’s been a lot more. DNA, automated facial recognition, iris patterns and many more. But all this has been accompanied by new technologies that have made it easier to collect, store and retrieve biometric data. That made it possible to use biometric data on the battlefield. Al Qaeda was defeated in Iraq partly because of a huge (several hundred thousand individuals) biometric database, collected during raids or after arrest by U.S. troops. This took anonymity away from many terrorists, and potential terrorists or terrorist supporters. Made it much easier to run down the bad guys later.

Nonsense.

I don’t recall whether that was actually possible on Kirk’s Enterprise, but in practice I don’t believe they ever beamed anyone or anything directly from one place to another – the transport process always went through the transporter pads aboard the ship. It wasn’t until The Next Generation that site-to-site transport became commonplace.

And, of course, proton torpedoes were what Luke Skywalker used to blow away the Death Star.

Phasers could also be set to kill, in addition to stunning a wide area.

Photon torpedoes were physical objects that had to be manufactured. They were meant for ship to ship battles. In the case of bad individuals there was the transporter, which was ship to ship or ship to shore; or the ships phasers could do a wide dispersion beam ship to shore to stun a large area.

But no, that would be illegal because they wouldn’t have had a trial, so it’s better to photon torpedo them while you have the chance.

Kirk would never use Photon torpedoes on individuals. That is what the trasporter was for, once locked in, the malcontents could be transported directly into the Brig, or deep space.

The BCTs (Brigade Combat Teams) of 2003 had little to no ISR (Intelligence, Surveillance, and Reconnaissance) capability, no top secret/sensitive compartmented information communications channel, inadequate intelligence analysis capability, limited human intelligence capabilities, and no properly equipped signals intelligence (SIGINT) platoons.

Most importantly, the BCT has ample
bandwidth available to handle internal communications and to provide reachback to division and EAD (Echelons Above Division) intelligence architectures. BCT
commanders can now truly prosecute a multidisciplined intelligence fight and use tipping and cueing from all collectors to focus FMV ISR assets better, thereby improving agility and ability to gain and maintain contact with the enemy.
