DBS wrote:The best evidence for the Borg having personal KE shields is severalfold, though.
1.) The Borg may well have encountered projectile weapons in the past, and thus may already have adaptations to them. (speculative, I know, but bear with me)
2.) The Federation has the amazing TR-116, a projectile weapon.
3.) These weapons can be replicated, and people with knowledge of the weapon have in fact fought against the Borg. (Worf)
Given the assumption that Starfleet is not stupid, and that when they are desperate to find any way to stop the Borg (including hand-to-hand), someone would have suggested trying them. The only explanation I can give without violating my assumption is that for some reason projectile weapons do not work well against the Borg, at least no better than energy weapons or fists. Moreover, after Picard had his tommy-gun success, why did he not attempt to replicate them for the crew if they would work in the future?
Your attitude seems to boil down to one of "the Borg must have fought against projectile weapons at some point, and they're still around" and "the Federation can't be that stupid". I can sympathise with both, but unfortunately the on-screen evidence does not indicate Borg drones possesing kinetic shields.
The first point can be countered with typical Borg tactics - amble slowly toward the enemy and rely on weight of numbers to win the day. If you think no-one would ever be that stupid to rely on such tactics, consider the 1st July 1916.
On the second, Federation ground equipment is notoriously poor - they have no artillery, no armour, no machine-guns or equivalent, no body armour (not even helmets!). Their only projectile weapon fits the profile of an assasination weapon more than an assault rifle. their tactics are so poor that the Jem'hadar (the run-at-the-enemy-screaming-brigade) are a threat to them. Unfortunately the theory that the Federation is indeed that stupid seems to be borne out.
