2-15. The Army gives the combatant commander depth and versatility. Because land forces can conduct a broad range of operations on a large scale, Army forces offer the combatant commander multiple options to achieve national military objectives. These capabilities include combinations of armored, mechanized, motorized, airborne, and air assault formations; attack as well as lift and reconnaissance aviation; special operations forces; and long-duration sustainment. With their ability to combine diverse capabilities for specific mission requirements, Army forces provide the combatant commander with tailorable and scalable force packages to address a broad range of possible contingencies. This simultaneous use of a broad range of friendly capabilities from across the Army, the joint force, and unified action partners creates dilemmas and narrows options for both adversaries and enemies.
