FORT BUCHANAN, Puerto Rico— As the Army’s home in the Caribbean, Fort Buchanan plays a vital role in supporting readiness, mobilizations, and regional operations across the Western Hemisphere and beyond. Installation leaders continually emphasize the importance of safeguarding sensitive information in an increasingly complex security environment.
Stephanie Acosta, the installation security specialist, leads the personnel security, information security, and operations security (OPSEC) programs. Acosta began her career as a backup security specialist in 2021 and assumed her current role in July 2024.
“Operations security is a security and risk management process designed to prevent sensitive information from getting into the wrong hands. We live in a culture where even small pieces of information could be vital to our adversaries and compromise our mission. Every day is OPSEC day, and protecting information is a responsibility we all share, “said Acosta.
Acosta emphasized that Fort Buchanan remains operationally relevant, particularly amid increased military activity in the region.
“We have recurring mobilizations that occur out of Puerto Rico, especially now. With the current climate and the uptick in military movement, we should not be sharing specific details about the increased military presence in the region,” she added.
OPSEC is a shared responsibility across the workforce, service members, and families. Information that may seem minor, when shared publicly, can be pieced together to reveal vulnerabilities.
“We need to limit information to a need-to-know basis. That especially applies to social media. Photos can unintentionally reveal locations, access points, or vulnerabilities that could be exploited,” Acosta said.
Families also play a critical role in protecting information, particularly during mobilizations.
“We don’t want to publicize the location where someone is mobilizing or deploying to. When we share that information online, we’re giving it away freely,” she added.
Acosta encouraged the Fort Buchanan community to remain vigilant, practice situational awareness, and report suspicious activity.
“Be precautious. Be vigilant. Safeguard our service members and families and always be mindful of the information you share—online, in conversation, and in your daily activities,” she said.
As the Army’s home in the Caribbean, Fort Buchanan’s security depends on collective awareness and disciplined information sharing to protect missions, people, and partnerships throughout the region.
Fort Buchanan supports approximately 15,000 military personnel, including active-duty, Army Reserve, Puerto Rico National Guard, Marine Corps Reserve, and Navy Reserve members. The installation’s mission is to enable readiness and facilitate the deployment of forces anytime, anywhere.
