How to use AT guns on the offense?

[FLG]

Some players might consider moving other units into the hex to draw def fire before moving the AT gun "gamey", but any unit in T mode is so vulnerable that this maybe the only way.

Interesting, I always thought of it as providing supressing fire or launching a diversionary attack to allow the AT unit to get into position and deploy. What does anyone else think? Is this generally considered gamey, I hadn't thought about it like this before.
