- I echo these questions. The drive-line-under-the-turret-basket problem is
- an obvious downside of putting the drives in the bow, and putting the sprockets
- in the rear of the vehicle also protects them from both head-on enemy fire and
- possible damage when the vehicle crests an obstacle and comes down hard. There's
- also the issue of weight-distribution, though I imagine the drive portion is
- a small percentage of the total vehicle weight.
-
- The Soviets copied rear-drive from Christie and used it on the BT-series and
- T-series - and maybe the JS-1,2, and 3...and I remember that at least one
- author I read commented on the Germans' efforts to copy the T-34 as having
- manifested themselves in a more "German, front-drive configuration" in the
- Panther.
