Its always a bother when your vh is dead, you can't get in the air because you're being vulched, and your town is 100% down and the enemy lets troops out and takes your base. Even if your vh is up you still have to drive all that way or if you do get airborne you still have to fly to town which is highly unlikely if there are enemy planes around. So since fields have mannable ack maybe towns could have mannavle ack so you can defend it a bit easier.
