As the U.S. deploys an armada of ships and aircraft to the southern Caribbean, at least partly aimed at Venezuelan dictator Nicolas Maduro, the U.S. Navy and Marines are conducting an amphibious landing training exercise in southern Puerto Rico. While the U.S. Marine Corps does not make any mention of Maduro or Venezuela in its media release about the exercise, the move comes as tensions are mounting between Washington and Caracas over the flow of illegal narcotics. The Trump administration considers Maduro a “narco-terrorist” and has raised the award for his arrest to $50 million.

Meanwhile, the U.S. carried out a lethal strike in the southern Caribbean against a drug vessel that departed from Venezuela and was operated by a designated narco-terrorist organization, U.S. Secretary of State Marco Rubio said on X this afternoon, following comments made by U.S. President Donald Trump. Striking this vessel points to a new kinetic angle to this effort, a major escalation. You can read more about the attack in our story here.
The amphibious training exercise, which began two days ago, involves Marines and sailors from the 22nd Marine Expeditionary Unit (MEU). The 22nd MEU, part of the Iwo Jima Amphibious Ready Group (ARG), left Norfolk Aug. 14, bound for the southern Caribbean. That force included more than 4,500 sailors and Marines on three ships: The Wasp class amphibious assault ship USS Iwo Jima, and San Antonio-class amphibious transport dock ships the USS San Antonio and USS Fort Lauderdale.
The Marines and sailors involved in the training exercise are part of the ARG/MEU dispatched for the drug interdiction effort, a Navy official told The War Zone Tuesday afternoon. The three ships are currently near Puerto Rico, the official added. Given the training efforts, at least some of these vessels are almost assuredly taking part, though neither the Navy nor Marines could immediately confirm that. The Navy referred us to the Marines for clarification, and we will update this story with any pertinent details provided.

The deployment of the ARG/MEU is part of a much larger movement that also includes three Arleigh Burke class guided missile destroyers, a Ticonderoga class guided missile cruiser, a Los Angeles class fast attack nuclear submarine as well as land-based surveillance aircraft. The movement of equipment and personnel is part of Trump’s continuing efforts to take on cartels.
The Puerto Rico training exercise “is designed to enhance the 22nd MEU’s readiness and capabilities, while also fostering stronger relationships with the Puerto Rican National Guard,” the 22nd MEU said in its release. “Amphibious operations are a cornerstone of naval integration and a core competency of the 22nd MEU. They enable the rapid deployment of Marines from naval vessels to shore, supporting U.S. strategic objectives.”
Whether coincidental or not, there are many physical and environmental similarities between Puerto Rico and Venezuela, located about 500 miles south of the U.S. territory.

“The challenging terrain and tropical climate of Puerto Rico provides an ideal environment for the 22nd MEU to conduct realistic amphibious training and hone specialized skills such as patrolling, reconnaissance, and survival techniques, ensuring a high level of readiness while forward deployed,” the unit explained. “These operations offer a valuable opportunity to train alongside the National Guard, leveraging existing military training facilities on the island. The 22nd MEU is actively seeking ways to expand collaborative training opportunities, including jungle training, combined exercises and community engagement events. These combined efforts are aimed at enhancing regional security, disaster response capabilities, and joint capacity building.”
In addition to the ARG/MEU ships, Arleigh Burke class guided missile destroyers USS Gravely and USS Jason Dunham are underway in the southern Caribbean, the Navy official told us.
Meanwhile, at least two Navy warships have reached or transited the Panama Canal. The Ticonderoga class guided missile cruiser USS Lake Erie recently passed through the canal from the Pacific to the Caribbean. The Panama Canal opens up into that body of water about 600 miles southwest of Venezuela.

In addition, the Arleigh Burke class guided missile destroyer USS Sampson is docked on the Pacific side of the canal, the Navy official added. Citing Navy policy against publicly disclosing the location of its submarine force, the official would not comment on the whereabouts of the Los Angeles class fast attack submarine USS Newport News, also part of this effort.

While there is no indication that the U.S. plans to land forces in Venezuela, has the deployed capacity to do so effectively, or that any U.S. vessels are close by, Maduro and his military say they are ready to repel any attack.
“In the face of this maximum military pressure, we have declared maximum preparedness for the defense of Venezuela,” Maduro said Monday of the deployment, which he characterized as “an extravagant, unjustifiable, immoral and absolutely criminal and bloody threat.”
Maduro called the U.S. buildup “the greatest threat that has been seen on our continent in the last 100 years” in the form of “eight military ships with 1,200 missiles” targeting Venezuela.
While the exact nature of this movement remains unclear, and no overt threats of kinetic action against Maduro directly have been made by the Trump administration, the Venezuelan dictator seems to be gearing up for a fight. Late last month, he announced the planned deployment of more than 4.5 million militia members around the country. They are volunteers designated to bolster the armed forces’ defense against external and domestic attacks. In addition, Venezuela announced it was deploying 15,000 troops toward the border with Colombia to conduct counter-drug operations.
Rubio said recently that “for the first time in the modern era,” the U.S. government was “truly on the offense” against organized cartels sending drugs to the United States, The New York Times noted. He and other officials in the Trump administration have called Mr. Maduro an illegitimate leader and his government a “narco-terror cartel.”
Maduro was indicted in a New York federal court in 2020, during the first Trump presidency. He and 14 others, including several close allies, were hit with federal charges of narco-terrorism and conspiracy with the Colombian FARC insurgent group to import cocaine. The U.S., as we previously mentioned, has issued a $50 million reward for his capture.
Last week, someone with direct knowledge of the operations told us that the U.S. is building up military assets in the region aimed as a direct message at Maduro in addition to taking part in counter-drug operations. With the aforementioned attack on a Venezuelan cartel drug boat, this has now become a lethal drug interdiction effort.
