58 and US M60 light machine guns both in 7.62×51mm NATO, replaced the obsolete BAR and Savage models, though the heavier Brownings were retained as platoon and company machine guns. The Israeli Uzi 9mm submachine gun was also given to armoured crews, Police BECAT teams and EEBI "Commando" troops, who were also issued the US Remington Model 700 Sniper rifle 7.62×51mm, and the Ithaca Model 37 12-gauge and Remington Model 870 12-gauge pump-action shotguns. Hand grenades were supplied by the Americans, who provided M59 "Baseball" hand grenades, Mark 2 Fragmentation Hand/Rifle Grenades, M61 Fragmentation Hand Grenades, M67 grenades, M26A1 Fragmentation Hand Grenades, M34 White Phosphorus Smoke Grenades and M18 Smoke Hand Grenades; M18A1 Claymore Antipersonnel Mines were also employed. The Nicaraguan infantryman was also provided with two types of portable rocket weapons, the shoulder-fired US M79 "Blooper" 40mm single-shot grenade launcher and the expendable anti-tank, one-shot US M72 LAW 66mm. Mortars and artillery Guardia infantry and artillery formations were equipped with a variety of crew-served weapons. Light mortars ranged from the M2 60mm and M1 81mm models of World War II-vintage, to the more recent M29 81mm; some selected elite troops received the Israeli-designed Soltam M-65 120mm heavy mortar. They were also issued US M18 57 mm, M20 75mm, M67 90mm and M40A1 106mm recoilless rifles. The field artillery battery was provided with six to nine World War II-vintage M3 37mm towed anti-tank guns, four US M101A1 105mm towed Howitzers and an unspecified number of EDESA Yarará 70mm 42-tube multiple rocket launchers of Argentinian origin mounted on Chevrolet C-10 Cheyenne 4×4 light pickups whereas the Anti-Aircraft battery operated US Maxson M45 Quadmount turrets on towed wheeled trailers and Israeli-supplied Hispano-Suiza HS.404 20 mm autocannons mounted on the TCM-20 turret configuration. Usually installed on the back of cross-country vehicles, such weapon systems proved useful in the direct fire supporting role, particularly against fortified positions and to root out snipers from urban buildings. The AA battery originally fielded six to eight M1 Bofors 40mm Anti-Aircraft guns, but these were re-fitted in 1979 to a civilian cargo vessel commandeered from the Memnic Line Company, in order to provide direct fire support off the Pacific coast to Guardia infantry units fighting in the Southern Front. It is also rumored that the anti-aircraft battery received from Israel in 1977–78 an unspecified number of surplus US-made General Dynamics FIM-43 Redeye man-portable surface-to-air missiles (SAM).
