The GIF looks like she is imitating a pump action 12 guage. Aiming high targets the upper body. It's going to be messy. My military training was slightly different. Since the targeting is normal, squat or lie down and target lower body. A wounded combatant tied up more resources.

That's good to know! I was making a layered commentary as usual. It's not entirely literal. 🤓
