Does anybody doubt the penetration power of the 3.7-inch HAA gun? Did the demonstration consider how the 3.7-inch HAA gun would fit into the highly mobile battles where
mobility and
survive were the watchwords?
#1 Lots of people, including senior Gunners, have claimed that the carriage could not cope with fire in l;ow trajectory or the lack of sights.
#2 Anti tank guns don't usually do a lot of movement, even in mobile battles. The deploy and fire from where there. Hooked in guns and detachments in unarmoured tractors are vulnerable to just about any thing.
#3 There is a father ted phenomena related to survivability
https://www.youtube.com/watch?v=MMiKyfd6hA0 A 2 pounder or 50mm pak is smaller than a 3.7" or 88mm HAA. But the HAA can open fire from far away.
A 6 pounder gun has a height of 1.28 metres and a width of 1.8 metres. At 1000 meters it subtends and angle of 1.3 mils vertically and 1.8 mils horizontally.
A 3.7" Gun has a height of 2.5 metres and a width of 2.4 metres. At 2000 meters it subtends and angle of 1.25 mils vertically and 1.2 mils horizontally.
They are just as hard to see at the range at which they will engage a tank in per terrain as per the Western Desert.

The Pz.IV firing HE in a support role was a threat to soft targets not pantsers. The British had CS pantsers to do the same job. The Pz.IV can still lob his HE from behind the hill, or sand dune, or whatever - thus putting out of reach of a direct-fire 3.7-inch gun despite being within range. Given the Germans already used the 88mm as an ATk weapon, understanding its capabilities and value on the pantser battlefield, I'm sure they already had a plan in mind should the British show up with a troop of 3.7-inch guns. I imagine the Germans would probably have come up with a workeable solution on the hoof before the battle had ended. The idea that a handful of 3.7-inch guns would have been a game changer is, in my mind quite daft. The 88mm was not a game changer for the Germans either.
If you want to talk about indirect fire solutions to identified anti tank positions, use field artillery not tanks. British CS tanks in the western desert lacked the range to engage HAA guns at 2,000m and neither British nor German tank crews were professionals in the indirect fire business. I don't know the probable error in range for the 75mm L24 firing HE. Do you, or anyone else on the board dedicated to Axis forces point me in the direction of an HE range table for this gun?
It was not easy to accurately estimate the range or location of objects in the desert. Field artillery was surprisingly survivable, especially when firing alongside tanks. I read of an account of The Chestnut Troop RHA brought up its 25 pdr guns in support of the Grants at Gazala firing over open sights. All guns survived unlike half the Grants.
The capability of the 88mm gun to hit tanks at long range cast a profound psychological shadow over British and American tank crews. It may not have been a game changer, but it tilted the table. Owning a weapon system that worried the enemy is generally a good thing.
