Phase-disruptors were handheld directed-energy weapons used by the Cardassians.

These weapons were considered less "elegant" than phaser-based weapons; their effects were thermal shock and blunt force, as opposed to the "rapid nadion effect." As a result, phase-disruptors inflict more damage to matter, but less damage to shields, than phasers inflict.

These weapons came in two styles, a pistol sidearm which was kept in a holster, attached to the Cardassian uniforms and a larger rifle. Rifles had a 3 millisecond recharge and 2 beam settings: stun and kill. They could also be fitted with an optional shoulder strap.
