sentences:  Ten UR-416 armoured cars were acquired from West Germany by the El Salvador government between 1971 and 1975 and were employed by the Salvadoran Army in Counter-insurgency and internal security duties, including patrol and road convoy escort roles, during the Salvadoran Civil War.For additional protection against RPG-2 and RPG-7 anti-tank rounds, some of the vehicles have been fitted with wire mesh screens, which detonate the HEAT warheads of the PG-2 and PG-7 projectiles before they came into contact with the vehicle's armour body.Salvadoran UR-416 armoured cars are normally armed with a M2HB .50 Browning (12.7×99mm) heavy machine gun mounted on the roof, sometimes fitted with a shield to protect the gunner, whilst some vehicles also have in addition a M60D machine gun (7.62×51mm) and shield mounted on the roof at the rear.
