Okay, while that story may be true, since you are both using trollies, I don't believe they can't go as fast as you. Momentum and all that. They have a better max strength than you do. Also, this is a case of firefighters, where you are not going to be able to put it on a trollie, but your back. And you only get one trip per person, not multiple. Just like how I don't like that there are female infantrymen now. I don't really think they will be able to carry someone that is 270lb or so including…
I remember one time, my team (US Army), fucked up, don't remember what we did. But, after PT in the morning, we had to go into our team leaders room, and stand in the corners staring at the wall at attention while he ate his breakfast and watched TV. I think it was for an hour or so. Fucking terrible, I'd rather be smoked (do pushups and other shit).
Well first, you want to open your hand, but keep your fingers semi-split (you need that airflow), then you wind up your arm with some kinetic energy, you then swing your hand to your targets face. edit: Don't forget to follow through the target with your hand.
