Johnny Weirzbowski...aka Off Ramp.

Private Johnny Weirzbowski is well known conscript among the troops. A infamous getaway driver who was given the option of the army or jail. He was put into the motor pool, of course, and made to drive wounded men to MASH units.

He was good at his job of course-very good. He managed to save more than a few men's lives. However, when trying to avoid shelling-he spontaneously generated the ability to create extra dimensional portals. After that, he did an even better job at getting men to and from places. The boys nick named him 'Off Ramp.'

Of course, the Nazis would love to have their own portal makers...
