The photographic documentation revealed by Agenda Malvinas last Wednesday, the 9th, on the runway of Malvinas Argentinas International Airport —where military equipment and tactical backpacks with MOLLE webbing belonging to the U.S. Army were documented—marked the beginning of a deeper story. Hours after that publication, sources at the airport confirmed a symmetrical movement: the dispatch of a similar shipment of military equipment to Buenos Aires, revealing a continuous circuit of U.S. military personnel entering and leaving the capital of Tierra del Fuego.

Qualified sources close to the Ushuaia Naval Base confirmed this Thursday, the 10th, that this is not an isolated technical visit. In recent months, a regular pattern has been established that replicates, with greater intensity, the practices observed during 2024 and 2025: the systematic arrival of small cells of between 20 and 30 personnel from the Marine Corps (USMC) and special forces under the Southern Command (SOUTHCOM) .
The footprint on the ground: valleys, glaciers and the BIM 4 site
Military sources consulted specified the scope of the maneuvers that the American troops are carrying out in the far south:
Deployment in plain sight and stockpiling of equipment
Far from adopting protocols of discretion or civilian camouflage, the US military delegations display a deliberate physical ostentation. Their members move through the Tierra del Fuego airport terminal with regulation Coyote Brown bags and Olive Drab duffel bags with visible locks and military markings, openly contrasting with the luggage of the thousands of tourists and residents who use the airport.
The decision not to conceal their presence constitutes an explicit political message about the territory . Added to this is a critical operational element: the troop replacements enter the country with communications equipment, sensors, and military technology which, after the training rotations are completed, remains stored in the depots of the 4th Marine Infantry Battalion in Ushuaia, creating an incremental stockpile of equipment with no apparent public inventory.
The constitutional violation: decrees instead of Congress
The core gravity of this presence lies in its legal framework. Article 75, section 28, of the National Constitution clearly establishes that the authorization of the entry of foreign troops into the territory of the Republic and the departure of national forces from it corresponds exclusively to the National Congress , a principle meticulously regulated by Law 25,880 .
The current scheme circumvents parliamentary oversight and democratic debate in defense committees:
The incessant transit of marines through the local airport runway and their training on the Fuegian glaciers demonstrates that the alignment with the Southern Command is not limited to diplomatic declarations; but is consolidated as a foreign military presence in the strategic heart of bicontinental sovereignty.
