Given the following context:

Note: the story is told from the viewpoint of Corporal Robert Dunne.
Tough-as-nails career Marine Sergeant John Stryker is greatly disliked by the men of his squad, particularly the combat replacements, for the rigorous training he puts them through. He is especially despised by PFC Peter "Pete" Conway, the arrogant, college-educated son of an officer, Colonel Sam Conway under whom Stryker served and admired, and PFC Al Thomas, who blames him for his demotion.
When Stryker leads his squad in the invasion of Tarawa, the men begin to appreciate his methods. Within the first couple of minutes of the battle, the platoon leader, Lt. Baker, is killed only seconds after he lands on the beach, PFC "Farmer" Soames is wounded in the leg, and PFC Choynski receives a head wound. The marines are aggressively pinned down by a pillbox.
Able Company commander Captain Joyce takes charge and he begins to send out marines to silence the pillbox. As a result of three unsuccessful attempts to reach the pillbox, two demolition marines and a flamethrower operator are killed and PFC Shipley is left mortally wounded in the line of fire. Sgt. Stryker takes action and demolishes the pillbox. Shipley would eventually die of his wounds in front of his best friend Regazzi (Wally Cassell).
Later on, Thomas becomes distracted from his mission, and "goofs off" when he goes to get ammunition for two comrades, stopping to savor a cup of coffee. As a result, though he brings back coffee for his squadmates, he returns too late — the two Marines, now out of ammunition, in the interim are shown being overrun; Hellenopolis is killed, Bass badly wounded.

answer the following question:

Who is the soldier that is wounded due to the marine goofing off? 

Bass
