Iron Man MK-VI

Iron Mar Mark-VI armor appears in Iron Man 2 the movie. This armor changes the arc reactor hole to a trianglular shape instead of the traditional circular one. The armor also upgrades its artillery to include a grenade launcher on one arm, a missile launcher in a shoulder and metal-slicing super lasers on both. The color scheme is once again the classic red and gold.[60] This armor is destroyed during the attack on Stark's house in Iron Man 3. (source)

Review: S.H.Figuarts Iron Man 2 - War Machine

War Machine 1st appeared in Iron Man #118 (January 1979).

War Machine

In Iron Man 2, Terence Howard is replaced by Don Cheadle as James Rhodes. During Tony's possible last birthday party before his death, Tony becomes extremely reckless at the thought of his little number of days left. Rhodes dons the Mark II, which he hinted towards wanting to wear it in Iron Man. After stopping Tony, James brings the armor to the US Military, who want to have it to use as a weapon. Justin Hammer upgrades the suit and finally, at Hammer Expo, shows the upgraded Mark II, dubbed the War Machine, along with drones with the Iron Man design. Ivan Vanko takes control of the armor and drones and uses them to attack Stark. After that, Black Widow breaks into Hammer Industries and releases Rhodes from control by Ivan. Iron Man and War Machine then work together and defeat the drones and a superpowered Ivan Vanko. (source)
