Key ideas in Mastering the Steel Giants
- Steering is achieved by slowing or stopping one track while the other continues to move
- A thrown track renders the tank completely immobile and vulnerable
- The tank pivots toward the slower or stationary track
- Repairing a track requires the crew to exit the vehicle and perform heavy manual labor
- Ground pressure limits determine where a tank can safely drive
- The 'Hull Down' position hides the vulnerable body while leaving the turret visible
- How steering is achieved through track speed differential
- Obstacles don't just stop a tank; they can physically break the drive system
- Using a reverse slope protects the tank from direct horizontal fire
- The danger and consequence of throwing a track
- Identifying terrain hazards that disable a tank
- WWII tanks lacked modern stabilization and required a momentary halt for accuracy
- The driver must time the stop to avoid the tank 'rocking' on its suspension
- Steering is achieved through track speed differential
- Tanks have a maximum fording depth before the engine drowns
- Tanks cannot climb vertical walls or slopes exceeding roughly 30-35 degrees
