((I scowered the internet to find German tank commands. You're the gunner, so I tried to translate your commander commands in English. I'm German, so this was pretty easy.))

Your commander sits behind you, Arnold von Richton. He peers through his vision blocks, the visibility a hindrance to his duties as a commander. The loader, Kurtz, loads a Pzgr-39 into the breech, giving a thumbs up to Von Richton. Meanwhile, Roland the driver, resides in the hull. The assistant driver and radio operator, Lichtman, waits patiently along side him. Von Richton's patience rewards him, spotting a distant column of IS-2s. He taps your shoulder without looking, still eying through his vision ports.

— Achtung! Panzer vor, Reichweite!

(Attention! Tank front... Range!)
