One of the weak points of tracked military vechicles are the metal plates. They need to be repaired after every 250 miles while constantly shaking soldiers inside the vechicle. This is about to change for rubber tracks are more durable and convenient while allowing the tanks to use less fuel. According to Treehugger, fuel consumption could be improved by 1/3 by using rubber tracks on MPG tanks and APC’s. There are limitations though since the rubber tracks are only strong enough to be used on vechicles up to 30 tons. Yet.
If you happen to have a tank with steel plated tracks, you still have a few days to upgrade it so it meets the new standards.
