Very nice work, mate. :) I agree about keeping the power claw. Given that an apothecaries primary task is to to see to the injured a spear would make less sense as it's a bit unwieldy to hold in your off-hand whilst administering to a wounded marine. Having said that, by the same token the claw is probably a tad risky for the patient if, in the heat of battle, he forgets his left and right. ;)
