Good (left), a communications corporal with 131 Commando Squadron Royal Engineers, British army, help build a defensive obstacle during exercise Red Dagger at Fort Indiantown Gap, Penn., June 13, 2016. Combat engineers enhance a force’s momentum by physically shaping the battle space to enhance a unit’s use of space and time while denying the enemy unencumbered movement. Exercise Red Dagger is a bilateral training exercise that gives Marines an opportunity to exchange tactics, techniques and procedures as well as build working relationships with their British counterparts.
