Nichols

Private Nichols is the main protagonist in Call of Duty 3, he was first seen in a camp near Saint-Lô, with Pvt. Leroy Huxley, and other soldiers. There Huxley teaches Nichols and Travers to shoot, and throw grenades. Nichols later has to bash a crate open to get a Thompson Submachine Gun. He and his squad then load into the truck being driven by Pvt. Huxley. This is when Nichols is first introduced to his sergeant, Frank McCullin. They are introduced to his "rules", and they start off for Saint-Lô. On the way to Saint-Lô, the truck his squad is in gets hit by German artillery fire. It rolls, and when Nichols comes to, Cpl. Mike Dixon is pulling him to the regroup position. There Sgt. McCullin is giving orders to Pfc. Salvatore Guzzo. Nichols then gets his orders and get boosted over a wall into the fight routing the Germans out of Saint-Lò. After fighting in the battles of the Falaise gap, Nichols is loaded onto a truck and is met by Guzzo and Huxley as they are promoted as well as Nichols himself, then eventually Nichols is rotated out for rest and relaxation. He may have been killed later on in the war but it is unknown.

Saint Lo
The first battle Nichols fought in was the Battle of Saint Lo. Nichols didn't get into the action until he was to take point followed by his fellow troops. He headed into a house and was tackled by a German soldier. After fighting off the German, Nichols called his troops into the house. The Nazis were filling the house and Nichols cleared them out. McCullin rewarded Nichols for his doings and heroic ways in the battle.

The Island
After the charge, Nichols and his troops are forced into a trench to clear out Nazi forces. He is later cut off from his forces, and later found by McCullin.

Chambois
In the Battle of Chambois Nichols and his squad protects Chambois after the Germans retreat there. At Chambois, Nichols and his squad protects Guzzo at a point and later finds Guzzo wounded after throwing flares so air support can help them but Guzzo would have been killed. There Dixon saves Guzzo's life but after that Dixon gets shot and dies.

Trivia

 * Some people believe that Nichols is the soldier at the front of the Call of Duty 3 case, but this has not been confirmed. He may also be on the back of the case, as the infantryman locked against a Wehrmacht soldier.
 * Nichols is the first playable character to speak in-game by telling McCullin "Sarge, it's Nichols." when McCullin tells Nichols "Good job,Nixon.".
 * Nichols is most likely the Character seen at the end of the level "The Forest" because near the end there is only one other soldier in the pit with the Mortar, and it is definately not Guzzo, who is talking to Dixon as he (Nichols) and Huxley watch them.
