I liked the John Wayne bars,basically chocolate ultra-whipped till the cocoa butter was dry,with oatmeal added for strength/rigidity,& they were Very Rigid,lol!The concept was so we could have un-melted chocolate bars,They didn't melt & they also floated!The woobie & Poncho combo was the Best invention since the Jeep,IMHO!The steel cleaning rods for the A-1's were a big hit on Bivouac or B-tours!Cosmoline is Still used today, though,I've Never met anyone short of 1st Sgt.,who liked it!The Internet was derived from our Military,that has to be #1!
