The battery case works if it is shimmed with a piece of cardboard the thickness of a cereal box lid...$11,000.00 and change and have to use a cardboard shim. Our poor troops. Although they probably have spare battery holders at $696.00 a pop. Having spent a lifetime in the military and government I thought I'd seen it all. Stoners weapon system turned to crap because using the wrong powder, troops wasted at desert one because pilots couldn't fly while maintaining radio silence, the shuttle exploding because of the low bidder providing o rings but in my wildest dreams I never thought any company in the United states would mark up a $2 part $694.00. Oh wait I forgot about the drug companies...there really is no shame. All the while FLIR is waving the American flag.
