Just finished a good book called Death Traps, unfortunatly have taken it back and do not know author now. He was the liason officer resposible for getting damaged tanks repaired and replacements back into fight. In a nutshell our tanks stunk and because the crews were so shot up we ended up grabbing infantry with as little as 3 hours training putting them into battle. Small wonder hit percentages were what they were. Only our ability to repair and lack of fuel for Germans made ther difference in armor
