By late 1944 a British division had 72 Bofors guns
Not quite as fancy or high tech but with an assortment of 20mm guns
Things were a lot less fun for the dive bomber pilots than when this was the standard light AA gun.
I think in the Battle of France there were 4 of these per battalion?
And there were a few tripods in each company.
No extra guns, just a few tripods to use for AA using some of the guns from the squads/platoons.
After France and when the gun supply got better they put two Bren guns on the light trucks, German pilots shook in their flying boots when faced with those.
