Crews perform preventive checks and services as modified for the climate and terrain. Rapid battle damage assessment and repair is critical to sustaining an attack. 3-106. Establishing aerial resupply and forward logistic bases may be necessary to sustain maneuver operations conducted at great distance from a unit’s sustaining base. This often occurs during an exploitation and pursuit. 3-107. Raids conducted by ground maneuver forces within the enemy force’s support areas tend to be audacious, rapidly executed, and of short duration. Logistic support is normally minimal when units conduct raids. Units conducting raids should carry as much petroleum, oils, and lubricants and ammunition as possible and take advantage of any captured enemy supplies. Once a raiding force crosses its LD, only limited, emergency aerial resupply of critical supplies and aeromedical evacuation are feasible because of the absence of a secure ground LOC. Commanders must thoroughly plan for aerial resupply of a raiding force, since it entails greater risk than normal operations. Under these conditions, units typically destroy damaged equipment that is unable to maintain the pace of the operation. Health Service Support 3-108. The burden on medical resources increases due to the intensity of offensive operations and the increased distances over which support is required as a force advances. Medical units must correspondingly anticipate large numbers of casualties over a large geographic area. The employment of weapons of mass destruction will greatly increase casualties. Mass casualty situations can exceed the capabilities of organic and direct support medical assets. To prevent this from occurring, planners should anticipate this possibility and coordinate with area support medical units for additional support. Additionally, units should plan and rehearse nonstandard casualty evacuation procedures. Effective management of mass casualty situations depends on established and rehearsed mass casualty plans and detailed medical planning. There are a number of other variables which can ensure the success of a unit’s mass casualty response plan. These include—  Coordination and synchronization of additional medical support and augmentation.  Prior identification and designation of the projected casualty collection points.  Quick location and clearance of the injured.  Effective emergency medical treatment.  Accurate triage and rapid medical evacuation of the injured to medical treatment facilities at the next higher role of care. PROTECTION 3-109. Protection preserves combat power. Commanders address the twelve protection tasks during their planning, preparation, execution, and assessment of offensive operations. They protect their forces and critical assets by synchronizing, integrating, and organizing protection capabilities and resources. The synchronization and integration of area and local security tasks, operations security, air and missile defense, and cyberspace and electronic warfare operations is essential to protecting the force. 3-110. Various military organizations provide complementary and reinforcing protection capabilities in an economy-of-force role to protect LOCs, convoys, or critical fixed sites and radars. Bases and base clusters employ local security measures, but they may remain vulnerable to bypassed enemy forces. These forces may require commanders to employ tactical combat forces when their threat requires a friendly response beyond the capabilities of base and base cluster defense forces. 3-111. During the conduct offensive operations, commanders place special emphasis on protection tasks related to survivability and detention operations. All units are responsible for improving their positions, regardless of role or location. 3-112. Commanders ensure that their units can perform assigned tasks in CBRN environments. They establish, train, rehearse, and exercise their units under CBRN conditions before deploying into a theater of operations and during temporary lulls to build Soldier confidence and competence in these environments. Leaders and Soldiers know the challenges associated with wearing protective gear. Commanders integrate CBRN reconnaissance and surveillance into their overall information collection plans.
