I try to do that often, easy enough when they are pinned. But it's frustrating as hell when your upright infantry who aren't pinned are getting crushed by T-34's charging them head on.
There is a technique to crushing, which is in the video
supra. If your opponent knows what he's doing and you can't get out of the way, sometimes you just need to retreat
Anti-tank snares are pretty common for Allied infantry, so unless you're trying to crush lone shocks, penals, or paratroopers, you're just inviting a damaged engine.
RE T-34s: the best is using ram to plow through a blob of infantry en route to the vehicle you're ramming. Oh so beautiful.
