The 22nd Marine Expeditionary Unit is assisting in the construction of an airfield on the former parade grounds at Camp Santiago in Salinas, Puerto Rico, with construction beginning earlier this month and having cleared large segments of land, according to an X post by @SA_Defensa shared between 12:16 AM and 12:45 AM UTC on January 1. The post, geotagged to Camp Santiago in the United States, states the Marine unit's role in the ongoing airfield project at the site located in Puerto Rico, as reported in the 29-minute reporting window ending at 12:45 AM UTC. This development follows previous reports of disputed U.S. Air Force F-22 deployments toward Puerto Rico on December 31, though no direct connection has been confirmed, according to social media posts cited in earlier updates from San Juan.
