Rooker

Private Rooker was an American soldier of the United States Marine Corps during World War II, seen in Call of Duty: World at War.

Biography
Rooker was the radioman of the Marine Raiders rescue team led by Sgt. Tom Sullivan and Cpl. Roebuck, which made a raid on Makin and saved Pvt. Miller. Later during the assault, the squad met a bunch of "dead" Imperial Japanese soldiers in the jungle. Sergeant Sullivan told Rooker to call with his radio another squad, in order to check if they already cleared that area. When Rooker was going to use his radio, a signal flare rose, blinding everyone. Sadly, Rooker is then stabbed with a katana. However, Pvt Livingstone or even Corporal Lozano sacrifice themselves for Rooker if they survived. Depending on Pvt. Livingstone, Rooker can move on in life or die with a katana stuck in him.

His weapon in Semper Fi is an M1 Thompson.

The radio operator at the end of Relentless is also named Rooker, and is a Sergeant. They are more then likely two Marines. In this level he uses an M1 and a Colt M1911.

Trivia

 * Keep Pvt. Livingstone alive and he will die instead of Rooker. Then, Rooker will get on the boat with Denny.
 * In the 1.6 patch it seems Rooker can die when assaulting the two MG posts by the beach. He is then replaced by a random Marine. The reason for this is unknown as Rooker always went with you to the ambush site. Also, it is quite hard for him not to die during the assault. However he still shows up in Relentless as the radio man. Perhaps there are two Rookers or maybe Rooker was injured in Makin then promoted to Sergent.
 * Rooker may sometimes get up from being wounded by the katana, however this is very rare.
 * It is possible to keep Pvt. Rooker alive and he will just sit were the mg nests are, keep Pvt. Livingstone alive and he will get killed by the fake death soldier and at the end he will get on the boats after blowing up the bunker. This means that he isn't K.I.A.
