You know about the Vehicle Drop commander asset in BF2? It was removed in FH2, but we could add it back with two options; one named Armour Drop and one named Transport Drop. They would be faster to load than the artillery and supply drop option, maximum 30 seconds in my opinion and the commander would drop them in a jiffy, one after one all over the places where the infantry has landed.
Nice idea on the armoured jeep, note the rotabuggy I suugested before, which could both be made easily with tweaking the original jeep from FH2. Also some improvements of the Bren carrier could be satisfying, like a light AA weapon mounted on it or sth like that.
