Welcome to the Imperial Gua-I mean, Army!So we're going to be regarded as an inferior mortal who will always be at fault for the mistakes the Astartes make no matter what?
Especially for pre primarch space marine legions like the 9th which reveled in how barely human they were.
Although, to be fair, this sort of thing happened a LOT IRL, shining example, Rommel, who'd turn off his radio so he could sally forth until the fuel ran out -_-
