Stealth quietly killing exes

The cloaked woman drove the tip of her nightstick into one ex’s spine, right at the base of the skull. There was a sound like driftwood breaking and the dead man fell forward. The stick whirled in her hand and smashed back and forth across the other ex-soldier’s jaw. She kicked its rifle into the air, dropped below its hands, and swept the legs out from under it. It landed on its back and she drove the rifle barrel through its eye, putting all her weight on it. There was a pop of breaking bone and the M16 sank into the dead man’s skull. It went limp.
