"Field Manual (FM) 4-30.51/Marine Corps (MCRP) 3-17.2A prescribes the doctrine for dealing with the unexploded ordnance (UXO) hazards on the battlefield. Use the information in this manual to teach military personnel, Department of Defense (DOD) civilians, and contractors about the UXO hazards they could meet and the procedures they can use to protect themselves. This manual also gives guidance on how to get help to take care of the hazards that affect mission capabilities. When personnel find UXO, they must follow these steps: 1) Note characteristics of the UXO hazard for purposes of identification. 2) Take immediate action (mark and evacuate). 3) Report the UXO hazard using the Explosive Hazards (EH) Spot Report (See chapter 4). 4) Use protective measures against the UXO hazard, if required. Based on these steps, FM 4-30.51/MCRP 3-17.2A serves as a general guideline for including UXO hazard procedures in unit standing operating procedures (SOPs). This manual provides information for transmitting and monitoring UXO reports throughout any battlefield functional area (BFA)."
