Here's an interesting point to consider guys. And it just might explain why coolant trucks are verboten to attack.
MASH units, rolling hospitals that help heal any wounded in sight, are never attacked.
Coolant trucks, rolling IVs for overheating BattleMechs that help any exhausted 'Mech in sight, or never attacked.
They are medical units, for BattleMechs. So you DON'T shoot them...
