If the British faction are stupid enough to go into an insurgency with a specialist anti-armour weapon without adequate backup and they lose it they deserve to get spanked by it.
Keep it as it is becuase:
- encourages thought on kits for the scenario at hand
- encourages teamplay to protect important kits
- provides a nice side-mission to re-capture stolen brit kits from an emplaced insurgent position
- Might actually get the brit faction to ease up on the armour strolling into town without recon, specific orders, or any infantry backup.
As the RGG guys often say "Molotov"
The HAT-Insurgent Turret will continue against all badly thought out strategies

(credit goes to bond for that)
