Seems like this is a very convoluted version of the LE method of TAP, RACK,BANG.
And TS is correct the TRB method is to tilt gun, rack, and start firing again. My apologies for not recalling who developed this method. TRB came about in LE when LE began issuing semi-autos.
I have also found that the TRB method also works when one is trying to employ a sucker punch to an opponent. Tap on his shoulder........draw back your fist.........and BANG
