Executed by pressing two quarter-circle backward motions and all three punch buttons, Cammy goes into her counter stance. If the opponent strikes her, she counters by flipping onto their shoulders and snapping their neck. She then takes them down and snaps their arm with a reverse armlock. To top it all off, she spins the opponent around, grabs them by the neck, and brutally twists it.
Exclusive to this move, each time Cammy snaps/twists one of the opponent's limbs, the screen turns to negative (all colors inverted) - perhaps to emphasize the counter's brutality and the extreme pain felt by the opponent.
Like all counter attacks, the CQC is very useful in avoiding rush downs, as it counters various special attacks, as well as normal pokes. It can best be used as an anti-air to punish opponents who try to jump in on the player. However, the CQC itself is at a disadvantage against projectiles, armor breaking attacks and throws - as with all counters. Thus, the move itself must be used wisely and timed carefully by the user.
- CQC is a pun based on the term close-quarters combat, a tactical concept based around short-ranged or unarmed confrontations.
- The CQC is one of the two Ultra Combos to have an acronym name. The other one is Decapre's DCM.
- The inspiration of Cammy Quick Combination was possibly the Cannon Revenge, the two attacks are counters, do not work against fireballs and not against throws.
- The CQC is among the only two counter Ultra Combos in Super Street Fighter IV, the other one being Fei Long's Gekirinken.
- The Street Fighter X Tekken Cross Art version is an homage to and duplicate of Cammy's scene in Street Fighter II: The Animated Movie where she assassinates her target with an identical attack.
