[@Kafka Komedy] I'd say all of them are potentially feasible as far as tech goes, though the EM field's deflection probably wouldn't be too extreme, more like bending the bullets around the wearer (if they're not fast enough to hit the target before being deflected too much) than sending them flying off into the walls at each side of them, and we've already discussed the AI and scanners as being able to give accurate tips and strategies when fighting foreign enemies. The problem comes with fitting all of them into one relatively small device: at the very least, the jetpack and weaponry seem like they'd conflict with one another as far as moving parts go, but I'd suggest that the brain-altering aspects of the Pak could- and, since the back is not where the brain is located, arguably should- be moved to something mounted on the head, perhaps even within the brain tissue itself. There's also the argument that the EM field would disrupt the AI, but we have ways of protecting against EM interference in the modern age, so that's a moot point.
