Operation Patriot Press (OPP) is a large-scale, multi-component logistics exercise that provides realistic training opportunities for the US Army Reserve, National Guard, and active-duty components to enhance their logistical acumen and readiness. The exercise, which spans several months, focuses on sustainment and logistical readiness, including tasks such as transportation, maintenance, and medical support, and allows units to collaborate with local communities and support strategic objectives. By participating in OPP, National Guard units can improve their readiness, build cohesion with other Army components, and support broader Army Materiel Command sustainment initiatives, making it a valuable tool for modern military training.
