As of early 2026, the British Army has a stated fleet of approximately 288 Challenger 2 main battle tanks (MBTs), though only about half are considered operational.

To put that in perspective, the US Army has approximately 4,600 to 4,650 M1 Abrams main battle tanks.

The British Army maintains approximately 500 horses for state ceremonial and public duties, primarily split between the Household Cavalry Mounted Regiment and the King's Troop Royal Horse Artillery. These units are responsible for royal ceremonies, parades, and gun salutes.

This means that the UK Army has approximately 1.74 horses for each main battle tank, or about 3.5 horses for each operational main battle tank.

The US Army has about 236 ceremonial horses and mules but has made plans to retire 141 of them this year as a cost saving measure, leaving 92.

This means that presently, the US Army has nearly 20 main battle tanks for each ceremonial horse/mule. If the reduction occurs, the US Army will have 50 tanks for each horse/mule.
