War Machine Costume
Suit up in Marvel's heavy-duty, shoulder-cannon-wielding tactical armor.
Colonel James "Rhodey" Rhodes takes to the skies as War Machine, Tony Stark's best friend and a key member of the Avengers. Known for his heavy-duty, military-grade armor, War Machine is a popular costume choice for fans who prefer a gritty, weaponized look over the classic red-and-gold Iron Man suit. This guide helps you assemble his signature dark grey and silver armored aesthetic using a printed bodysuit, EVA foam armor, or a deluxe ready-to-wear suit.

How to put it together
- 1
Put on the base layer, which can be a printed War Machine zentai suit or a dark grey compression shirt and pants.
- 2
Secure the LED arc reactor to your chest so it glows clearly through the designated chest cutout or fabric panel.
- 3
Strap on the leg, thigh, and forearm armor pieces if using a multi-piece foam or plastic armor kit.
- 4
Attach the shoulder-mounted mini-gun bracket to your left shoulder, ensuring it is secure and balanced.
- 5
Put on the tactical boots and pull the leg cuffs or armor greaves down over the tops of the boots.
- 6
Slip on the gauntlets and gloves, testing the palm repulsor lights if your costume has them.
- 7
Put on the helmet, adjust the internal padding for a snug fit, and turn on the blue LED eye lights.
Makeup & hair
Keep hair short or slicked back so it fits comfortably inside the helmet. If you plan to pose with the faceplate open, groom your facial hair into a neat, military-style goatee similar to Rhodey's look.

War Machine costume FAQ
- What color is War Machine's armor?
- Unlike Iron Man's red and gold, War Machine's armor is a military-inspired color scheme of matte gunmetal grey, silver, and black, accented by a white or blue arc reactor.
- How do you attach the shoulder cannon?
- For DIY costumes, the shoulder cannon is best attached using a harness worn under the suit, with a magnetic mount or bolt protruding through the shoulder fabric to hold the prop.
- Is a War Machine costume hard to walk in?
- If using a printed fabric bodysuit, it is very easy to move in. Full-body plastic or foam armor suits require some practice to navigate stairs and sit down comfortably.
Did you know? In the Marvel Cinematic Universe, the War Machine armor was originally the Iron Man Mark II suit, which Rhodey confiscated and had heavily modified with military grade weaponry by Justin Hammer.
