The Portuguese Navy (particularly the Marines, known as "Fuzileiros") made extensive use of patrol boats, landing craft, and Zodiac inflatable boats. They were employed especially in Guinea, but also in the Congo River (and other smaller rivers) in Angola and in the Zambezi (and other rivers) in Mozambique. Equipped with standard or collapsible-stock m/961 rifles, grenades, and other gear, they used small boats or patrol craft to infiltrate guerrilla positions. In an effort to intercept infiltrators, the "Fuzileiros" even manned small patrol craft on Lake Malawi. The Navy also used Portuguese civilian cruisers as troop transports, and drafted Portuguese Merchant Navy personnel to man ships carrying troops and material and into the Marines.
