Possibly the least used vehicle in Conflict and yet it holds all the things players value most...
I'll try to keep it short, i would like to see the Arsenal truck connect with the Command truck to allow saved kit spawning. I think the "logistical trail" that this functionality provides would outweigh the 'OP' nature of full kit spawning that has been a issue in the past. The added supply cost requirement from Command trucks could force players to set up more expensive forward positions in order to feed full scale assaults. This also might start creating natural convoys where a Command, Arsenal, and Supply trucks are being driven together and would lead to bigger targets all around.
Secondary idea would be to allow the Arsenal truck to function as a Armory while on a friendly base by either being in the base proximity, or having a Deploy function that would give access. This would give a nice ability in that you could temporarily provide the advantages of a Full Arsenal, while also having the ability to stay mobile and "Turn the tap off" so to speak.
Really anything that gets some of these lesser used trucks on the road and driving around would be nice.
