> How do infantry get in and out of position?

They don't. Life expectancy of a Russian on the front line is hours. You just send in another wave.

If that were the case then there wouldn't be anyone there to receive the resupply to begin with.

		Also .. if that were the case russia would not find volunteers anymore, as the large majority of russian soldiers in Ukraine are there by free will, not because they were force drafted. Edit, I forgot, most are not aware of that: https://www.rferl.org/a/russia-ukraine-conscripts-war-combat...
