Tap Rack Patch ;-)

This is one that can get you into trouble and get you out of it by ensuring you never forget an important combat shooting skill.
Tap Rack is an important firearms drill that is learned during SOIT (Schoots Onderricht /Instruction de tir). When a weapon jams in a firefight, the first thing you do is a Tap Rack procedure. In other words the safest thing you can do to get your weapon operational and return fire as quickly as possible. The correct procedure is Tap (Push the magazine solidly into your weapon to get a misfed round ready) Rack (Operate the charging handle and assist as necessary to chamber the round) Bang (Pull the trigger and get that round downrange and into the enemy before they get theirs into you.
