The person has to get up to the vehicle first, which can be difficult if the pilot is better at shooting than I am, and then jump onto it and start punching. I think the infantry guy basically punches a hole in the armour, then drops a grenade in and the tank blows up. It levels the playing field a bit between infantry and vehicle combat. It actually works pretty well, believe it or not.
I was busy trying to figure out which button could get me out of the tank when it blew up. But at that point, I knew I probably wasn't going to be allowed to drive the tank again.
