Define Go/No-Go criteria - ✔✔Go: pertains to friendly criteria which must be met to accomplish the mission. No-Go: focus on the enemy factors and ability to affect a negative mission outcome meaning that the mission should be aborted or delayed. Define low, medium, and high threat environments. - ✔✔Low threat: allows tactical operations to proceed without prohibitive interference. Aircrews are free to select tactics that ensure effective use of weapon systems and ordnance. Medium threat: allows acceptable exposure time of friendly aircraft to enemy air defenses.

Traveling Overwatch - ✔✔TERF technique used when likelihood of enemy contact is possible and precautionary measures are justified, but speed is desirable. Characterized by continuous movement of the traveling element. Overwatch/cover element moves from covered position to covered position making maximum use of the terrain and vegetation. Bounding Overwatch - ✔✔Enemy contact is imminent and speed is not of the essence. Traveling and overwatch/cover element roles will swap as the flight moves along the route.
