I think we know all know why the 3.7 was'nt used as AT on a regular basis, it's just a question of if, when, how and why, the same as the German 88mm.The 3.7 had to be towed by the Matador 4x4 Tractor the same as Med Arty because of the weight, but it could and did trasverse soft ground (thats why Fairground people used them). so it would have to be dug in, ok if you new when and where the tanks were coming and had the AP ammo. As to getting the guns away if you looked like being overrun, it's the same as any Heavy Arty, if theres time ok, if not you dissarm the gun and go. P.S. On the 27th July 44 at Ondefontaine, my fathers, 5.5 Med gun Bty (Brewed Up) 3 German tanks. Rob D.
