I run this list as well and I think you have it nailed down pretty well. The only thing I might change, and its purely a preference thing, is maybe drop the jalopies for some
SP Bofors & another platoon of Universal Carriers. That way you get some mobile
AA in your list and you still have the 2nd UC unit taking over the recce duties from those jalopies. But... the jalopies are pretty cool looking on the table so maybe leave them in half the time
