Colombia faces rising threat from improvised drone swarms

Colombia is facing an increasing security threat from the use of modified commercial drones by illegal armed groups in regions such as Cauca and Catatumbo. These groups are utilizing a form of “warfare DIY,” assembling improvised attack drones using dual-use components like brushless motors and flight controllers sourced from Asian markets and brought in through smuggling networks.

Security experts warn that the proliferation of drone swarms—multiple devices operating in coordination—poses a significant challenge to traditional defense. Unlike isolated drones, swarms can approach from various directions and saturate surveillance systems, making it difficult for security forces to react in time.

To counter this, specialists suggest that Colombia must move beyond simple signal jammers, which may be insufficient against large numbers of devices. A more effective defense would require a multi-layered approach combining sensors, artificial intelligence, electronic warfare, and physical interception methods, alongside efforts to neutralize the ground-based supply chains and launch sites used by these groups.
