Colin's Halo/Army party

I always decorate for my great nephew & nieces that I always watched when they were little for their birthdays so they can come home to something special after school. I was told to do a Halo theme but evidently the army theme doesn't exactly fit that well with the Halo. So do your homework if you have a Halo theme. Evidently they fight aliens in space. And they don't lookalike Army men. They are more like Navy Seals. I only researched pictures of other parties after googling Halo. Do your homework if you don't have Halo games in your house.
