the primary weapon
to all starships in the federation, is basically refined lasers, hand held
phazors are mandatory for all away teams.
phazors have several settings, the only ones that stay true from show to show is stun and kill, however, many epiosodes add new settings for those just-in-case times,
intrepid class starship uses i believe 3 forward pazor arrays
and 2 aft phazor arrays
in a next generation one, riker sets his phazor
to somthing called setting 16, which suposedly would
destroy half a building.
