The main goals of a live wargame like this are to 1) learn lessons, and to 2) get everyone simulated combat experience. This means you need to run as many scenarios as possible and to make sure every unit gets to participate.
If Red team sinks all the landing ships on round one, does that mean your infantry doesn't get to war game and learn lessons (after all, the infantry are all 'in lifeboats')? Fuck no. You take extensive notes on what red team did, restart the war game, but this time mandate the infantry land. It would be a colossal waste to not learn lessons in your infantry unit or to not allow them to accumulate simulated combat experience simply because their boats sank in the first round.
The Russian sub from the first attack (not this one) has a few extra holes in it. :)
