Combat is replete with hazards. Assessing hazards is the primary challenge of combat operations. It is imperative to develop a process that identifies and assesses all variables before taking a course of action.
Modern warfare requires specialized units that depend on each other for support. When a supported unit requests action from a supporting unit, it is vital that the supported unit understand the level of risk incurred by the supporting unit to carry out the request. Furthermore, for the overall commander in charge of the two units to assess the risk of an operation, it is vital that he understand the specific risks incurred by each participant.
