Previous: Pursue the Jungle Train
Pretty easy if you remember to stay behind the rail car to the left of where you spawn, the tank can knock it back once but after that its a pretty good spot to stay and wait for the soldiers to move in. There are 10 escorts.
If you want to capture the tank, things are a little more difficult. It seems to be impossible to catch the Captain off-guard. The only way to pump tranquilizer rounds into him seems to be to face his fire and trust your recovery items to keep you alive. Or you could destroy (one of) the fuel tanks while he's out and then he's completely vulnerable? The good news: two shots to the head with the Mosin Nagant (Rank 3) seems to do the trick.
