This should be the new tank class in WoT. No armaments, but they can move roughly the same speed as medium of same tier and can restock a selected ammo type such as AP, APCR, HEAT, etc,. If they get destroyed, they will always ammo rack unless they have offloaded all rounds. Their explosion is twice as large as a regular ammo rack explosion. Since they wouldn’t need a turret, there would be no turret to blow off. To balance these little kamikazes of doom, there can be only one per team and you have to pay for the ammo that was delivered, say you delivered ammo to the T92 HMC, you would pay the shell price for each shell delivered even if unused. There would be very few players of these things, but their benefits in-game could be massive. The only way to earn XP and credits while using these is from spotting, and assisting with reloading. Say for example a tank you resupplied damages/destroys a tank, you get the exact same amount of XP and credits as the tank that did it. The only two ways these things can do their own damage is ramming and, once all shells are distributed, kamikaze into enemy tank with a built in explosive. The kamikaze will always deal half a tank’s current hit points of explosive damage of course affected by damage range rolloff and items such as spall liners. If it gets destroyed, it will do twice the blast radius of regular ammo rack damage to all tanks in the area including allies. These can be used as scouts but have the smallest view range of all tanks of that tier and average radios. This was my random idea for a new tank class in WoT.
