I had a fun engagement with a Tiger 1. I saw him moving up a flank at the 135 spawn, so I took the scenic route and got behind him. He had no idea I was there. I shot one round into him (while still moving) which destroyed his gun. I then shot him in the side while driving past, shot him in the front, then shot him in the rear again. He wasn't able to follow me with his turret. Unfortunately my shots didn't kill him, and I had to bug out as he had a friendly Hellcat coming to help, but I dare say the M18 is superior than the tiger in some situations, particularly in GV battles that take place in larger, wooded terrain.
