You can try it yourself.
You can also try double mortarHTcs or isgs which rape all british emplacements even with permanent brace. But hell no, infantry should totally a-move into British emplacements just fine too, coz game is all about building blobs.
The funniest thing about this thread is that it is all about needing a nerf for a 400mp unit that can't move and is hard countered by a moveable mortar that causes barely over half as much manpower, and no fuel. It clearly needed nerf because the a-move blob of shrek death couldn't reliably kill it.
