 Operation security or OPSEC is critical to Army readiness and success. It preserves the effectiveness of military capabilities and keeps potential adversaries from discovering our critical information. Critical information must be protected to ensure the enemy does not gain a significant advantage over our soldiers. The elements of secrecy and surprise are vital to the accomplishment of our goals and protection of our soldiers. Maintaining OPSEC and keeping sensitive information out of the hands of those who wish to do us harm is everyone's responsibility. Everyone should be aware that the enemy obtains sensitive information from a variety of sources including casual conversations, internet dialogue and social media. For more information, go to the OPSEC homepage for tips and ideas on protecting sensitive information. We cannot afford to let our guard down. Our collective safety and security of our operations depends on you. Remember, OPSEC makes the difference.
