The South Georgia Island Revolution

Captain Noah Denmark looked over the landscape. It was... ugly. He called to a soldier to his left. The soldier took a peek over the edge of the sandbags, then he hopped over.
Almost immediately, a horrible moan shook the ground. What once seemed like fallen soldiers happened to be zombies, some of the zombie army (clad in red), and some were his own soldiers (clad in blue). The soldier screamed, letting loose with his musket (which basically meant he fired once), and as he realoaded, a zombie went upon him.
It was his commander, who had been lost in the field that month. He screamed, as they ate him and tore him to shreds. Denmark ducked down, and the zombies moved on. He motioned to the five remaining troops in his army. They switched to their handmade semi-automatic handguns. Denmark switched to his revolver rifle.
"FIRE!!" he yelled, and his troops emptied their clips.
Two zombies went down.
