Compression phaser rifle

Memory Beta, the wiki for licensed Star Trek content.

Compression phaser rifles are one of the most powerful personnel-carried weapons in the Starfleet arsenal and are an alternative to the type-3 phaser rifle. These powerful weapons are assigned to starships that could possibly see intense close-quarters or surface combat.

The USS Voyager was equipped with Compression Rifles as a standard part of its weapons inventory. They were first used by an away team which transported to the Caretaker's array in 2371. (VOY: Caretaker)

The crew of the USS Enterprise-E used Compression Rifles numerous times. These included warding off invading Borg, protecting the Baku, and assaulting invading Remans. (TNG movies: First Contact, Insurrection, and Nemesis)

The Compression Rifle was also the standard armament for Hazard Team members aboard Voyager from 2376 until the ship's return to the Alpha Quadrant.

On more hazardous missions, Starfleet officers carry the Compression Rifle as a greater source of firepower. The rifle fires pulses of a similar but more powerful type to the Phaser in a tight beam. The Compression Rifle also fires a more deadly and silent sniper shot, which requires more energy but can be very effective on infiltration missions.
