The Fighting Rifle book 1. The Fighting Rifle, #1

The subject matter is the use of a semi-automatic rifle in a combat environment or military, SHTF environment, and will also refer to Personal Defense Weapons (PDWs) as they have roughly the same format. This manual focuses primarily on the combative use of semi auto rifles, not marksmanship per se. You can take basic shooting courses with instructors who teach the finer aspects of using e.g., a 1-point rifle sling versus a 2 or even 3 point sling.
They focus on marksmanship aspects like different skills for e.g., transitioning a rifle from target to target, or advanced recoil management. I prefer to train students and focus on the combative aspect of firearm techniques. Yes, you need solid fundamental marksmanship skills, and you develop those when training anyway. What many students (and instructors) lack, is a better understanding of actual fighting techniques with firearms, in this case semi auto rifles.
Semi auto rifles that shoot rifle caliber rounds are designated as "carbines", in shooting circles it seems that rifles that shoot pistol rounds can also be referred to as pistol caliber carbine or PDW.
