Soldiers aboard M1A2 Abram Tanks from 1st Squadron, 4th Cavalry Regiment, 1st Armored Brigade Combat Team, 1st Infantry Division start to move out, as part of an Initial Ready Task Force (IRTF) exercise, at Johanna Range, Poland, May 20, 2019. An IRTF is similar to an Emergency Deployment Readiness Exercise (EDRE) but on a smaller scale. An IRTF is a no-notice, rapid-deployment exercise designed to test a unit's ability to alert, marshal, and deploy forces and equipment for contingency operations or an emergency disaster.
