Or with a tracked anti-tank vehicle.
I seem to recall one of this game's developers stating that the anti-tank units in this game represent massed anti-tanks guns on a narrow front. What the Germans called "Pakfronts". During the large Soviet armored attacks on the Eastern front in late 1941–1942, the Germans quickly realized that their anti-tank guns, operating individually or in small groups, and with no central commander, were quickly overwhelmed.
The pakfront concept was developed to counter this. A group of up to ten guns were placed under the command of one officer. He was responsible for designating targets and directing the fire of his guns. This allowed the Germans to spring particularly effective anti-tank ambushes, with all guns being assigned separate targets and then firing at once, maximizing surprise and minimizing the chance for return fire. These were then developed into even larger units.
The Soviets soon copied the tactic, and used it to great effect at the Battle of Kursk in July 1943. The tactic was found to be extremely effective, and the Soviets embellished upon it by using multiple pakfronts in co-operation with minefields, anti-tank ditches, and other obstacles to channel the enemy armor into their fields of fire. I'm thinking that this is what is represented in the game by the anti-tank units.
The problem with the anti-tank guns mounted on an AFV chassis, (tank destroyer concept) is that because they looked like a tank, everyone (including officers who should have known better) tended to treat them as tanks. I just got done reading American Knights, a book about the US 601st towed anti tank battalion that got upgraded to M-10 tank destroyers. The author of the book complained that were often taken out of their anti-tank role, and called upon to do everything the Sherman tanks in the armored divisions and battalions did, from overrunning infantry to bunker busting with the M-10s. I guess that explains why the tank destroyer concept got shelved at the war's end. Why have two different types of vehicles that do the same thing?
