Get the HMMWV mug.
Biggest piece of shit vehicle in all of the military banches. Tops out at 45 mph. Starts only 25% of the time and bogs out the rest of the time.

stands for high mobility multipurpose wheeled vehicle.

very good at off-roading. it's top speed is 55 mph although some hmmwv's can reach speeds of up to 75mph.

The engine sounds like a vacuum cleaner.

it likes to break down at inappropriate times or while just parked.

they like to catch on fire a lot, even without being damaged by an enemy.

plug in accessories (impact wrenches) are also prone to catching on fire.
