At a Civil War reenactment, a Union cavalry officer displays his gear.The equipment would be worn on the soldiers' backs as they fought and moved throughout the North and South. In the reenactors pack there is a bedroll (top right), canteen (turquoise circle on the bottom left), and rifle (without the bayonet, center).
