"High rank, but really in this place I don't see how it matters." Hell, she was pretty sure half the people here weren't even from her universe or timeline, so why should she try to pull rank.
She kept hammering as she tried to think of how to explain. "Imagine a metal crossbow, but instead of a bow, there's a long metal tube instead. At the trigger end is a metal bullet or round containing a small amount of explosive powder: pull the trigger and it sets off the heated compound at the end of the round. The heat stays inside the metal tube and the resulting pressure sends the round out the other side and onto whatever you have as a target."
She hoped that explained things. "It's why rifles and pistols are referred to as fire arms."
Sonya stopped her work to study the dagger she was sharpening and stuck it in the fire to soften the metal a little more.
