To describe it from the victim's point of view:GURPS 4e Day After Ragnarok, in Australia:
Japanese mini-sub caught napping, captured.
You're the sole crewman on board the sub. The other three left two days ago to go onto land on an uninhabited island, light a fire, cook some of the penguins there and generally relax a bit. You've been living with them in this sub for several weeks, making preparations for setting up an intelligence-gathering base here, 50 kilometres north of Sydney. They have never been more than a few hours before, so you're getting worried.
There's someone knocking on the hull in morse code, using the international signal book, saying "Surface." This can't be your crew, they have a code to tell you to let them in, so you've been found by the enemy! You blow tanks, which works fine, and start the electric motor. That doesn't go so well: the propeller's making lots of noise and no thrust.
You arrive at the surface. You grab your SMG and go out through the airlock, wanting to take a few of the Emperor's enemies with you. There's a large armed launch with crew on deck, who start ducking as you spray them with fire. Then someone in the same kind of diving gear as your crew shows up behind you, grabs you and takes you into the sea. He can breathe underwater and you can't, so you lose that struggle and are captured.
We'd put metal bars through the guards on the propellers so they could not turn and the sub could not run or ram. The propeller blades broke off. He didn't hit anyone with the sub-machine gun, although he broke a couple of windows on the MTB. He didn't try to scuttle the sub, probably due to the psychological effects of exposure to Serpent venom.
