This guide is written on behalf of US Marine Major R. E Hanley, who alongside his military career also taught football at Northwestern University. This 1942 guide is designed to bring America's fighting marines up to their physical peak before deployment. With clearly laid out illustrations and simple easy to follow text, it lays out the basis of Hanley's curricula. The material itself covers Ju Jitsu, defences against unarmed attacks, attacks with knives, batons and rifles with bayonets. It also includes the PT (physical training) regimen and how the combat Ju Jitsu content fits within that programme. Watch out for unique contextual techniques such as the 'Foxhole Takedown' showcase the Ju Jitsu as used against a bayonetting attacker whilst you're in a trench or foxhole
