An '''internal security vehicle''' ('''ISV'''), also known as an '''armored security vehicle''' ('''ASV'''), is an [armored car](/source/Armored_car_(military)) or [armored personnel carrier](/source/armored_personnel_carrier) used for supporting contingency operations.

== Design ==
[Internal security](/source/Internal_security) vehicles are typically armed with a turreted [heavy machine gun](/source/heavy_machine_gun) and auxiliary [medium machine gun](/source/medium_machine_gun). The vehicle is designed to minimize firepower dead space and the vehicle's weapons can be depressed to a maximum of 12°. [Less-lethal](/source/Less-lethal_weapon) [water cannon](/source/water_cannon)s and [tear gas](/source/tear_gas) cannons can provide suppressive fire in lieu of unnecessary deadly fire.<ref name="Brassey's">{{cite book|title=Brassey's Encyclopedia of Land Forces and Warfare|year=1996|publisher=Brassey's|isbn=1-57488-087-X|pages=56, 57|url=https://books.google.com/books?id=Ipz0AzERg_MC&q=%22internal+security+vehicle%22|author=Franklin D.

The vehicle must be protected against weapons typical of riots. Protection from [incendiary device](/source/incendiary_device)s is achieved through coverage of the air intake and exhaust ports as well as a strong locking mechanism on the fuel opening. Turret and door locks prevent access to the interior of the vehicle by rioters. Vision blocks, ballistic glass and window shutters and outside [surveillance cameras](/source/Closed-circuit_television) allow protected observation from within the vehicle.

Wheeled 4×4 and 6×6 configurations are typical of security vehicles. Tracked security vehicles are often cumbersome and can have negative political connotations for being perceived as an invading or occupying force {{Citation needed|date=October 2024}}.
