I have owned this paperback reference book for many years now,
and its one of my all time favorites. Written where a novice can
understand the training tactics by an author who is actually an
LEO himself. Topics include: proper mindset, multiple adversarties,
clearing room drills, wounded shooter techniques, using cover to
your advantage, and much-much more. A worthy read available
from Palladin Press for a'round $25~!
