ARMY TM 5-5420-212-10-1 MARINE CORPS TM 08676A-10/1-1 n. Rule 2. Lower the RRB to increase N. If there is ample tail clearance, some increase in N can be obtained by keeping the CRB  in  its  highest  position  and  lowering  the  RRB  to  its  lowest  position.  The  mathematical  equation  for  this  process  is shown under Table 3-34, column (k). N Rule 2a. = N Rule 1 + Value N calculated from the equation shown under Table 3-34, column (k) Table 3-34.
