A pincer move was a military maneuver in which a force spread out so as to attack its target from both sides simultaneously.
In an alternate 2266, the USS Enterprise and the USS Farragut planned to engage a Romulan Bird-of-Prey in a pincer move when it passed through the tail of the comet Icarus IV and became temporarily visible through its cloaking device. (SNW: "A Quality of Mercy")
In the Tamarian language, the pincer move was described by the phrase "Uzani, his army at Lashmir," referencing that earlier battle from Tamarian mytho-history. This could be further broken down as "Uzani, his army, with fists open," and "Uzani, his army, with fists closed." In 2368, Captain Dathon proposed this tactic to Captain Jean-Luc Picard to fight the entity on El-Adrel IV. (TNG: "Darmok")
