Colombian Ministry of National Defence has ordered 18 units of the ATMOS 155mm self-propelled howitzer from Israel’s Elbit Systems in a deal worth $101.7 million. Defense News reported that The decision came as a surprise for some observers who expected the contract to go to the Colombian Army’s preferred choice, the CAESAR six-wheel self-propelled made by French company Nexter. During final negotiations, Nexter informed Colombia that the value of the potential deal would be $114 million. That price was deemed too high compared to funding allocated to the acquisition program. Colombia ultimately turned its attention to the Atmos, and the parties reached an agreement within budget. Nexter did not respond to a request for comment.

The Colombian Army uses its artillery in real fire missions mainly attacking positions of Colombian drug cartels or ongoing battles between FARC (Fuerzas Armadas Revolucionarias de Colombia, the Revolutionary Armed Forces of Colombia – People’s Army) guerrillas and the government. The FARC is a Marxist–Leninist guerrilla group involved in the continuing Colombian conflict starting in 1964. About 2,000 to 2,500 FARC dissidents still take on FARC’s original doctrine and continue with drug trafficking, though far smaller than the group at its peak. A small faction of FARC leaders announced a return to armed activity on 29 August 2019. The Colombian government responded with preemptive strikes, killing FARC members planning to lead rearmament activities. The FARC lost 1,500 members in 2020. The number includes deaths, capture, and desertions. He said the FARC still had 2,500 armed members.
