typical in the u.s., afaik, is one or more handguns, a nightstick (the kind that has a small handle perpendicular to the main shaft toward one end), and often something like pepper spray. there have been at least a few programs to give tasers or similar things to some officers (e.g. only giving them to sergeants), but in several instances (at least one, anyway) taser use has resulted in death, which i think has slowed adoption.

i'd say it's not uncommon for officers to have rifles (M14 or similar) and/or shotguns at their disposal, probably in their car, but not something they carry. special units have rifles (M16), maybe automatic weapons, and maybe more elaborate non-lethal devices, such as tear gas or flash-bangs or whatever.
