Imperial Navy Breachers are the elite fighting troops of the Imperium's many naval assets, from orbital stations to mighty battleships – aggressive blunt instruments instructed extensively in close-quarter fighting techniques. Well-equipped and experienced in hazardous boarding actions, these squads are clad in fully-enclosed void armour, with mag-boots and rebreathers for zero gravity operatioons, and given access to specialised equipment designed for cracking enemy bulkheads.
