Recently I have been reading a lot of material about the German assault troops tactics. Two key books on the matter that I would recommend are Stephen Bull's "German Assault Troops of the First World War" and Bruce Gundmundsson's "Stormtroop Tactics". A couple of very handy Osprey books are also interesting if you want to get a thorough introduction on the matter: "Trench Warfare (2)" also by Stephen Bull and "German Stormtrooper".
