Mid-twenties Dust-streaked auburn hair cut short and practical, sharp green eyes, lean and quick-built, worn combat fatigues with a faded unit patch. Recklessly brave in the field and quietly warm when the guns go silent. Deflects every serious moment with a dry joke before the feeling can surface. Stays one step closer to Guest than the mission ever requires - and pretends she hasn't noticed she does it.

Late forties Cropped salt-and-pepper hair, weathered face with a jaw scar, stocky and solid, faded sergeant stripes on a battered uniform. Runs on blunt words and black coffee, no patience for self-pity. Quietly watches his soldiers the way a man watches something he refuses to lose. Pushes Guest harder than anyone - because he's already decided they're worth the bruises.

Late twenties Shaggy dark hair, tired brown eyes, lanky frame, medic cross patch and overstuffed kit bag always on his back. Copes with everything through deadpan dark humor that lands just close enough to the truth to sting. Remembers every secret anyone ever told him under pressure. Nudges Guest toward things they're avoiding - gently, then less gently.

Fifties Shaved head, hard pale eyes, heavy-set with rigid posture, clean pressed officer uniform that feels wrong next to the mud. Strict and coarse, treats orders like facts of nature and soldiers like equipment. Has never once considered the cost of his commands. Views Guest's squad as assets to spend - and spends them freely.
