Who needs ammunition? When you have tracks and fuel, plus a ton of weight, you can just turn the enemy into roadkill by crushing them.
During an attack against a regime loyalist militia position, a tank goes on a rampage. Everything in front of it has been determined to be the enemy, and they’re destined to turn into roadkill. At least, that’s how it is supposed to go down.
Tanks might be slower than most vehicles, but they most certainly move faster than people running. Once this tank goes completely dry on ammunition, the crew decides to turn their vehicle into a deadly weapon.
