Though universally referred to as the Bren Gun Carrier, the vehicle was actually designated as the Carden-Loyd Universal Carrier (hence other the used designation of Bren Universal Gun Carrier). As the Bren light machine gun was the standard squad support machine gun in service to the British Army, it was no wonder that the Bren Gun Carrier was fitted with one such weapon for self-defense. In essence, the Bren carrier was nothing more than an armed tractor, capable of hauling 4 to 5 personnel (or more in crucial wartime situations), supplies or wounded. Armor was relatively light throughout and, as mentioned earlier, no top cover was afforded the crew. In some cases, this covering was improvised by the crew to protect them from the elements. Steering was accomplished through use of a wheel as oppose to the levers found in tanks. This, naturally, made training of driving personnel a tad easier.
The vehicle would definitely go on to prove its worth time and again. The Ford 8-cylinder water-cooled gasoline engine provided enough hauling power on the worst of roads and in the worst of conditions. Add to this the well-designed suspension system and it becomes no wonder how this little vehicle made it into so many hands.
The Bren Gun Carrier was served with a single 7.7mm Bren light machine gun on a pintle mounting. The light machine gun could be swapped out in favor of the Boy's .50 caliber anti-tank rifle for defense and one variant in particular - the "Wasp" - was fitted with a flamethrower. Captured Bren carriers in German Army service were refitted and put back into service mounting the 37mm PaK anti-tank gun.
Bren carriers could be found on most fronts accomplishing just about any type of job including medevac, infantry support (mounting various caliber mortars), artillery tow vehicle, mobile command post and demolitions.
