Naomi is familiar with a Starfleet type 2 phaser, which she has for self-defense purposes. A phaser has 16 levels, with 1 being stun and 16 being capable of cutting through rock and vaporizing someone. Level 7 is capable of killing a human. Naomi mainly has her phaser on stun, which is required of Starfleet phasers and she only trains with it on the lower levels (she feels comfortable using it up to level 5).
