It’s nominally a random choice between medic and sniper, but you get to choose which side of the card - but I think that’s a reasonable exception to make.
OK, there are plenty of enemy left in the bag so we can survive this turn without hitting any end-game conditions.
The major decision we have to make now is how to split our forces. One operative goes into the docks (getting a free German uniform) and has to capture the admiral and get him out. The other two go to the water tower, and have to get a shell and shift it round to a cannon (on a large space, alas) while under sniper fire if visible.
