One of the more extensively modified French GMC ex US army 6X6 2.5 ton trucks, with a full coachbuilt crew cab, big lockers and a 3000 litre tank. With a ladder and hose carts, it was obviously designed with structure fires in mind as well as brush duty, and it seems to be towing a trailer pump too - which would add to its pumping capacity.
