Among the quickguides and infographs threads on /k/, there are occasionally more worthwhile and heavily detailed manuals posted. Several of these documents provide vast amounts of info on firearms, military equipment and military tactics. Here is a list linking to some of more notable and interesting manuals.

List of worthwhile manualsEdit Hundreds, literally hundreds of weapon operation manuals. This is an absolute goldmine of information; if you ever wanted to know how a particular firearm operates, even if it's only semi common, look no further (with the exception of eastern bloc firearms, in which case there is significantly less information). There is also a very good section about firearm optics and accessories like Aimpoint and EO Tech. Mainly information on US military tactics. Arguably one of the best books on squad based tactics.
