The British Army current operates 331 Challenger 2 MBT. A further 70 are in long term storage.Yep..
I'd be curious in seeing a breakdown / comparison between US and UK holdings of vehicles at the divisional level. I figure the UK had armoured / mechanized forces in BAOR, (the U.S. also maintained light infranty formations.) I never had the impression that the relevant UK formations were signficantly under equipped vs their U.S. counter parts. Was there a vehicle class where a U.S. Armoured or Mech Division had a clear advantage over a similar UK formation ?
I do acknowledge that the U.S. maintained a large fleet of helicopters and maintained heli borne formations that I don't believe had UK equivalents.
The U.S. Army currently operates roughly 4,000 M1A1/A2. Around 3,000 M1 are in storage.
The USMC operates 400+ M1A1/A2 despite the vehicles less than ideal features for amphibious operations.
The TOE for Royal Armored Corps Brigade size formations calls for 54 MBT in three squadrons (18 vehicles per squadron). The U.S. Heavy Brigade Combat Team (HBCT) has 64 MBT in four companies (14 vehicles per Company). Probably the most significant difference between the U.S. and UK armored brigades is the organic artillery. The HBCT has two batteries of SP 155mm howitzers (9 tubes per battery) and two 120mm SP mortar carrier companies (7 vehicles per company) along with an organic combat engineer element (two companies) while the British Armored Corps brigade has no significant organic artilley or engineer capability (this is a scenario that extends to the UK "Strike" and "specialized infantry" brigade structures vs. the U.S. Stryker and Infantry BCT TOE). The HBCT/SBCT/IBCT are designed to be a "turn key" formations, while the British Army 2020 brigades are not.
