In the grim darkness of the early 1990's, Warhammer 40,000's lore was less well developed and Citadel's model range was less extensive; the Warhammer 40,000 Rogue Trader rules allowed any Imperialor allied faction to take Dreadnought Armour, (AKA Mech Suits). Back then Dreadnoughts weren't Space Marine heroes' mobile sarcophagi, they were simply the most powerful form of personal armour and the pilots weren't permanently entombed in their Dreadnoughts.
