A Territorial Army team arrived gave pupils at Brington Primary School a rude awakening on Monday.
As part of the creative curriculum, Class 2, made up of children aged seven to 11, were starting work on the topic of World War 2.
The children, who were not aware of the plans until they turned up at the school, got to experience what life would be like if they had been conscripted into the army during the war. They were put through their paces with marching, drilling and an assault course.
Class 2 teacher Kirsten Carpenter said: “When we start a new topic, we always want to do something that has a bit of a wow factor. They got given dog tags to say they had passed at the end of the day. The children absolutely loved it.”
