From November 16 to 21, 2025, the United States Marine Corps 22nd Marine Expeditionary Unit conducted joint exercises with the Trinidad and Tobago Defence Force. The training, held just off the coast of Venezuela amid the Essequibo dispute and increasing U.S. security support to Guyana, serves as a clear regional signal.
The exercise features MV-22B Osprey tiltrotor aircraft for long-range tactical lift, AH-1Z Viper attack helicopters providing controlled fire support, and UH-1Y Venom helicopters handling command, light transport, and medical evacuation missions. Air assets coordinate with infantry, logistics, and signal elements to support coastal and inland operations, both day and night.
Night insertions require precise approach, light discipline, noise management, and electromagnetic control (EMCON) compliance. The AH-1Z Viper integrates with Trinidadian coastal surveillance systems and ground units to build a recognized maritime and shared operational picture. TTDF and U.S. fire-support teams align call-for-fire procedures and coordination methods.
The exercise’s proximity to Venezuelan waters gives it strategic significance. While it does not alter the balance of power alone, it demonstrates Washington’s intent to maintain rapid-reaction forces near the Gulf of Paria and Caribbean energy routes, while positioning Trinidad and Tobago as a key partner in maritime law enforcement, internal security, and conventional defense.
