I think a fighter/light bomber escort to attack and neutralize any airfields close to the landing zone before a landing would be a good idea. If we could get some priority air support, it would be excellent. Also, what would the carrying capacity of the gliders be? Maybe they could carry some motorcycles or light prime movers (like a Jeep) + towed artillery so that the Fallschirmjaegers get that extra punch and an easier way to move around.
