Joint Operations Across the Range of Military Operations V-47 (6) The sustainment requirements and challenges for forcible entry operations can be formidable, but must not be allowed to become such an overriding concern that the forcible entry operation itself is jeopardized. JFCs must carefully balance the introduction of sustainment forces needed to support initial combat with combat forces required to establish, maintain, and protect the lodgment as well as forces required to transition to follow-on operations. For additional and detailed guidance on forcible entry operations, refer to JP 3-18, Joint Forcible Entry Operations. e. Attack of Enemy Centers of Gravity. As part of achieving decisive advantages early, joint force operations may be directed immediately against enemy COGs using conventional and SO forces and capabilities. These attacks may be decisive or may begin offensive operations throughout the enemy’s depth that can create dilemmas causing paralysis and destroying cohesion. f. Full-Spectrum Superiority. The cumulative effect of dominance in the air, land, maritime, and space domains and information environment (which includes cyberspace) that permits the conduct of joint operations without effective opposition or prohibitive interference is essential to joint force mission success. JFCs seek superiority in these domains to prepare the operational area and information environment and to accomplish the mission as rapidly as possible. The JFC may have to initially focus all available joint forces on seizing the initiative.
