Pincer Movement

The pincer movement or double envelopment is a military maneuver. The flanks of the opponent are attacked simultaneously in a pinching motion after the opponent has advanced towards the center of an army which is responding by moving its outside forces to the enemy's flanks, in order to surround it. At the same time, a second layer of pincers attacks on the more extreme flanks, so as to prevent any attempts to reinforce the target unit. Most infantry combat, on every scale, is based in some fashion on this military tactic and it is commonly used by aircraft as well. Normally you would have the frontal blocked off and then attack the enemy using this tactic through either end.
