I agree with Nick on preserving a battlefield. I've only went to two battles so far (one for SCAT and one for DAK) and I'm hooked.

Every battlefield has areas that are "riskier" to drive on, in terms of damage to your own tank from the terrain. When we battle, tanks that are disabled (usually due to track issues) become pillboxes. Dead tanks stay dead when killed just once, and stay on the battlefield with transmitter off. The only exception we have is for tanks that roll or go into a deep gully. Generally, the tank is recovered immediately with the broken parts...
