There was room to fit a tank as well. They used to use a 110 to push a tank* out of a Herc if the tank engine failed.I’d always thought that too, so I looked it up. Its designation is ”Truck, Utility, 1/2Ton, 4x4 Rover Series III”. Earlier ones I suppose were IIA.
There must have been some seriously weedy helicopters when the requirement was raised, because even a full-size 110 and trailer fits with room to spare in a Herc. Early piston-engined Wessexes, I suppose.
* Tank. = big green tracked thing with a box on the top with a big gun within the box.
