I made this cake for a woman whose son loves to play Call of Duty, and it was for his birthday. It is a half chocolate and half confetti cake with buttercream frosting. The camo was done by first outlining the shape with butercream, then filling in and smoothing the butercream. The barb wire is fondant that was twisted together and small pieces of fondant were attached for the barbs. The tank and grenade are made from rice krispy treats covered in fondant. The dog tags are also fondant.
