All Russian soldiers are now space marines. Can ukraine survive for a week?

All russian soldiers. Immadiately, without warning, turn into space marines of the ultramarines chapter. And will serve the Russians.

The space marinussians are somehow supplied adequately and have their power armor.

Wincon for ukraine is NOT being defeated within a week. The russian wincon is the opposite.

Edit:I may or may not have fucked up with this. So the question is now wether or not EUROPE(besides the UK) can last a week.
