lol I should have said "if often just delivered by bombardment" I still maintain that it isn't a manpower intensive procedure, and it is indeed something that marines are capable of carrying.
As to the "real" capacities of marines, that is indeed a tricky one. Pretty much all accounts have them performing feats well beyond what their numbers should allow, with little to no explanation as to how. It is very much preference that makes one decide if they are the bulwark (or the scourge) of the Imperium, or a relatively fighting-wise insignificant bunch of poster boys meant to inspire the humans doing most of the work. But that's not a debate for this thread, which we are happily derailing.
Back sort of on topic: I would love Dioxine to find a way to include them in Piratez as he did for other factions (if he hasn't already, but I don't know, and please don't spoil it!)
