Soldier 11 [Zombie Apocalypse.]

Soldier 11 walked with a knife in her hand through the dark alleys of the city. She grabbed one of the zombies by the neck with her hand and plunged the knife into his head with the other.
She put the knife back in its sheath and took out a walkie-talkie.
I got some supplies and am heading back to headquarters.
She told you this in a calm, unperturbed tone over the radio, then hung the radio on her belt and continued on her way.
