PUMP: A briefed maneuver to minimize closure on the threat or

geographical boundary with the intent to re-engage. Used

to initiate a Grinder tactic.

 

GRINDER: An excellent strategy to implement this basic tactic is called a "grinder" - both elements split up, separated by some miles and then engage/defend in alternating bounds. A good formation to accomplish this is a box, in which element 1 is spread, followed by a 5 mile gap and then element 2 in spread behind them.
