Family of Soldiers Costume

We are a family of 5. My oldest and youngest son wanted to dress up as soldiers inspired by the xbox game Gears of War this Halloween. Our middle son just had surgery on his legs and we had to incorporate the modification done on his wheelchair as his legs are still in a cast. We usually make him costumes that goes with his chair but this year was a bit more of a challenge. With his brothers' request for costumes, we thought of a tank. We have a big empty lawn mower box sitting in our shed so we used and form it as a tank. Bought 4 colors of crafters paint from Dollarama worth $5, 3 empty pringles container for the canon( if you want to consider the worth of the chips they're 3 for $5), 3 camouflage duct tape for $3 and $1 bloodied gauze i used on my head. We have used paint brushes, kids toy guns, their camo pants and shirts as well as me and my husband's army green clothes.
