Phaser Rifles - With 15 additional settings, these weapons use the same components as a hand phaser, however, they are equipped with a large spot light, which is used for viewing of darker spaces, as well as a targeting cross hair. Unlike hand phasers, however phaser rifles can carry up to 6 energy packs at a time (hand phasers can hold up to one). Currently, there are two types of phaser riffles -- array, and cannon.
An arrayed phaser rifle fires a standard beam, much like a hand phaser. Phaser arrays can fire up to 80 meters away. A cannoned phaser rifle fires a pulse of energy, which can reach targets up to 300 meters away. Cannoned rifles have a larger range, and, can fire more rapidly than an arrayed phaser rifle.
Phaser rifles come in Type III, Type IIIH (arrayed) and Type IV, Type IVH (cannoned)
Force Field - A forcefield is a layer of energy which surrounds a mass. Most things can not penetrate a forcefield, unless they are at a specific power modulation. Most forcefields are set to a random modulation. Forcefields can easily be taken down by a phaser on the same energy modulation, however, with random modulations, this is almost impossible unless the computer automatically changes the modulation of the phaser to match (which can only be done by authorization of the Commanding Officer.)
