A technical is an improvised fighting vehicle built from a civilian motor vehicle. It is typically a light (pickup) truck with a tripod-mounted heavy machine gun on the back. However, they can be built on other types of civilian vehicles (e.g. an SUV, or a medium flatbed truck etc.) and there are many other types of weapons that could be mounted on-board. Technicals are mostly associated with irregular and paramilitary forces. The etymology of the term is uncertain, but it is believed to have originated in Somalia in the 1980s or '90s.
If identifiable, try to tag the weapon and vehicle too.
Weapons commonly mounted on technicals include:
