Guatemala Receives First Lot of More Than 2,000 M4A1 Carbines in First US Arms Purchase in Decades

Guatemala's army on Monday, 21 September 2026, formally received a first lot of more than 2,000 carbines bought from the United States, at a ceremony in Guatemala City attended by President Bernardo Arévalo, the defense minister and the US embassy's chargé d'affaires. The weapons are M4A1 carbines, the type carried by US forces, and arrived aboard a US Army aircraft, according to Infobae. The handover took place on the military ramp of the Guatemalan Air Force at La Aurora International Airport.

The order was placed through the US Foreign Military Sales program and paid from Guatemala's own budget. The US chargé d'affaires stressed that Guatemala was investing its own resources and called the purchase "historic", the first of its kind in about five decades, Prensa Libre reported.

The itemized order, as published by La Hora on 22 September, with the rifle figure also carried by the government's Diario de Centro América, comprises:

• 2,699 M4A1 rifles, US$3.61 million
• 59 M240 machine guns, US$1.05 million
• 57 grenade launchers, US$165,453
• 11,220 30-round magazines, US$205,101

The total comes to about US$5.03 million, according to La Hora. The grenade launchers had already arrived in an earlier lot, and the next lot will be the machine guns, the defense minister said. Arévalo described the acquisition as more than 14,000 units of modern armament within an investment of more than US$5 million, and said deliveries will continue over the coming months until the full order is received.

The equipment is destined for the new Special Jungle Operations Brigade (Brigada Especial de Operaciones de Selva) in Petén, the northern department bordering Mexico. The brigade's missions are counter-narcotics operations, guarding the border with Mexico and protecting natural resources; its installation in Petén is in the final stage of construction, the defense minister told La Hora. The kit also includes communications systems of Israeli technology and helmets with night-vision mounts, according to Diario de Centro América. The US chargé d'affaires said the delivery is part of a larger effort to field nearly 8,000 additional rifles to strengthen 16 Guatemalan battalions, and linked it to the US-led Coalition of the Americas against cartels, Prensa Libre reported.

The purchase ends a restriction that Arévalo traced to November 1977, under Public Law 95-148, the foreign assistance appropriations act for fiscal year 1978 passed by the US Congress, adopted over serious human rights violations during Guatemala's internal armed conflict, according to Diario de Centro América. AP reports that the United States blocked arms sales in 1978 over massacres of civilians, and that truth commission reports held the army and paramilitary groups responsible for 97% of deaths in the 1960-1996 conflict. Diario Las Américas reports that the conflict left some 200,000 dead and disappeared, that Washington lifted the ban in March 2026, and that despite the embargo the United States kept donating equipment to Guatemala's armed forces for counter-narcotics work. "The army of today is fundamentally different from the army of 1978," Arévalo told AP. In August 2026, a United Nations working group on enforced disappearances urged the Guatemalan government to open the army's wartime archives, according to AP.

Guatemala ranks 104th of 221 countries in GlobalMilitary.net's ATLAS Index of military power, with a score of 14.2 out of 100; its armed forces number 18,050 active personnel and 63,850 reservists. Arévalo said that since 2024 the army had seized more than 34,000 kg of cocaine and more than 6,000 firearms and disabled 16 clandestine airstrips, Infobae reported.

Further lots are due over the coming months, with the machine guns next in line. The defense minister said Guatemala also expects in future to acquire aircraft, boats and other special equipment; the defense ministry had said it planned to spend about US$52.2 million this year on arms and equipment for the armed forces, according to Infobae.
