Appendix A UXO OBSTACLE NUMBERING UXO hazard areas are integrated into the standard obstacle numbering system using the procedures described below. Army and Marine Corps use the same numbering system. Army units are used for example only. a. Obstacle Numbering from Other Echelons. FM 90-7, Combined Arms Obstacle Integration, covers obstacle planning (and numbering) from corps through task force (TF) level. A theater Army (TA) or joint task force (JTF) headquarters (HQ) could give an obstacle to subordinate units as specified tasks. The solution is to add other options for the unit type (Character 1) in the 12-character obstacle number. In this case "T" for TA or "J" for JTF. Thus, the number for a bridge demolition (span) obstacle (planned) designated by 4th Army is T004-**A-BS0l/. Additionally, other joint force HQ can use this system (e.g., a MEF could use "M").
