One day during the 62nd National Tournament

The match Kuromorimine vs Pravda is ongoing in heavy weather. The battle is taken to a very narrow cliff road. You look out of your Tiger 1's cupola and suddenly hear the road partially collapsing. Koume's Panzer III is sliding down the cliff and into a river. Referees can't intervene due to the heavy weather conditions and poor visibility. At the same time, Pravda's tank advance and are about to engage the flag tank (you). What do you do?

you can hear Koume's crew over the radio in distress as water enters their tank
