that's a good point, more than anything they do look like stikkbombz.

i would dispute this only because they're mechanically attached and wired to his armour, however they could be stikkbombz attached to the armour as a self destruct mechanism in case the occupant is killed - not in terms of preventing someone getting the tech but to continue killing posthumously :)
