Laugh I was nearly crying, a few points.
1) Buying a Mule costs naff all, Big Dog how much excluding R&D.
2) You might have to go find the mule but at least it tried to stay alive when attacked.
3) The big one
The Mule can happily carry/find its own food supply Big Dog cant plug in for a recharge because the recharge vehicle cant get there Duhh



Think about that one unless its nuke powered one day in & its finnished, perhaps it carries solar panels. just the ticket under a jungle canopy.
Sorry Suhiir had to pinch it
