Get it right, the troops didn't want shock gloves, their boxes are for live ammunition in order to kill people. They wouldn't use a "less-than-lethal" tool like shock gloves because they don't see Iranians as people.
I assume the artist is also ignorant of the fact that the U.S. isn't running out of "ammo", as in small arms ammunition for frontline troops; we're running out of missiles and bombs because we're too cowardly to actually get within firing range of the enemy.
