    Weekly Events

    Our operations simulate real deployments lasting from 8 to 10 months with weekly missions written and built by experts based on current geopolitics.

    Every combat unit within our structure is required to stay up-to-date with their knowledge and a weekly squad drill is hosted for squad leadership to evaluate and coach their members.
