Perhaps at first the Imperium underestimates the threat of whatever we are fighting and sends in 1 SM company to deal with it. That one company gets wiped out to the last astartes without really achieving anything, perhaps this causes the Imperium to react by sending in several regiments of IG. But other than reasons like that, I dont think we should put SM in the campaign.
