Organizes army

“The monsters are coming,” I said. “And they’ll kill everyone in this town if they can. Unless we kill them first.”
The crowd let out a sound that was a lot like a hungry growl.
I found myself smiling, more and more widely. Yeah, the world was full of monsters and demons. But it was a human world. It was our world because we were the cleverest, most resourceful, and most dangerous things in it. Maybe my little army wasn’t the most martial representation of humanity, but people fighting for their homes had, historically, done incredible things.
Time for history to repeat itself.
“Sanya, raise your hand.”
He did.
“This is Sanya. He’s a Knight. He fights monsters for a living and he knows what he’s talking about. Sanya is your commander. Sanya . . . hey, where the hell did you get a freaking Kalashnikov?”
Sanya shouldered his rifle by its strap, grinning. “Found it.”
I waved a hand at him. “Whatever. Take charge, man.”
“Da,” Sanya said, and raised his voice to a bellow. “Hello. First of all, da, I am Russian. Cope. Second, you see these men and women in uniforms? Easy to recognize even in haze, da? They are your officers. I will make groups of about thirty. Each group get one officer. Officer tell you what to do, you do it.”
Sanya turned to the uniformed men and women. “You guys get to give one of three orders. Stand, retreat, and follow me. Keep it simple. Communications in battle are hard, even for professionals.”
There was a round of nods. The military folks looked grim. They knew what a clusterfuck they were about to march into. And I knew about how hard it is to convey even simple ideas in a fight. We’d be lucky if the volunteers could follow even those limited orders reliably.
Sanya turned back to the crowd. “Everywhere we go tonight, assume that you have orders to kill the enemy on sight. If standing, and enemy comes, kill enemy. If retreating, kill enemy. If following officer and enemy comes, kill enemy.” Sanya considered. “Basically tonight we are always killing enemy.”
Another laugh at that. But he was playing to an easy room. People who are scared need to laugh, and the scarier things are, the more they need it.
“Okay!” Sanya called. “Officers will divide you into groups! Everyone keep quiet so you can hear them!”
Sanya and his officers started getting them sorted out.
