Type 3D Phaser Rifle

 

Sometimes referred to as assault rifles, the The Type-3d utilizes plasma acceleration to provide a powerful bolt of energy similar to that fired by pulse phaser cannons on the Defiant-class starship, and at variable power levels. The Type-3d phaser rifle is a much larger, more sophisticated weapon than Type-3b. It uses an advanced computer control system to allow for modulation characteristics to be modified faster than in previous phaser rifles, important when dealing with the Borg. The rifle has a range of 600 meters.
First placed in service in 2373, the Type-3d Phaser rifle also includes a much more effective and elaborate targeting system and a larger energy reserve over the Type-3c. The Rifle is equipped with a gyro-stabilized targeting unit. This targeting unit incorporates sensors capable of detecting and tracking life forms and can perform the equivalent of tricorder short range biological scans. Images of the targeted life forms would be displayed on the units display screen.

The Type 3d is being phased out as the main rifle for Starfleet Officers and relegated to a reserve roll, with the introduction of the Type-3e. Many Starships have a small supply of these aboard, usually stored aboard large auxiliary craft, such as Runabouts, and in small weapons lockers.
