Joint Operations Across the Range of Military Operations V-45 accustomed to having attachments may be required to provide administrative and logistic support to normally unrelated units. (3) The CCDR, in coordination with Commander, United States Transportation Command, subordinate JFCs, and the Service component commanders, needs to carefully balance the desire to retain unit integrity through the deployment process with the effective use of strategic lift platforms. While maximizing unit integrity may reduce JRSOI requirements and allow combat units to be employed more quickly, doing so will often have a direct negative impact on the efficient use of the limited strategic lift. In some cases, this negative impact on strategic lift may have a negative effect on DOD deployment and sustainment requirements beyond the GCC’s AOR. A general rule of thumb is that unit integrity is much more important for early deploying units than for follow-on forces. d. Forcible entry is a joint military operation conducted either as a major operation or a part of a larger campaign to seize and hold a military lodgment in the face of armed opposition for the continuous landing of forces. Forcible entry operations can strike directly at the enemy COGs and can open new avenues for other military operations. (1) Forcible entry operations may include amphibious, airborne, and air assault operations, or any combination thereof. Forcible entry operations can create multiple dilemmas by creating threats that exceed the enemy’s capability to respond. The joint forcible entry operation commander will employ distributed, yet coherent, operations to attack the objective area or areas. The net result will be a coordinated attack that overwhelms the adversary before the adversary has time to react. A well-positioned and networked force enables the defeat of any adversary reaction and facilitates follow-on operations, if required. (2) Forcible entry normally is complex and risky and should therefore be kept as simple as possible in concept. These operations require extensive intelligence, detailed coordination, innovation, and flexibility. Schemes of maneuver and coordination between forces need to be clearly understood by all participants. Forces are tailored for the mission and echeloned to permit simultaneous deployment and employment. When airborne, amphibious, and air assault operations are combined, unity of command is vital. Rehearsals are a critical part of preparation for forcible entry. Participating forces need to be prepared to fight immediately upon arrival and require robust communications and intelligence capabilities to move with forward elements. (3) The forcible entry force must be prepared to immediately transition to follow-on operations and should plan accordingly. Joint forcible entry actions occur in both singular and multiple operations. These actions include establishing forward presence, preparing the operational area, opening entry points, establishing and sustaining access, receiving follow-on forces, conducting follow-on operations, sustaining the operations, and conducting decisive operations.
