H-151. Units report protective obstacles through their chain of command to their higher level headquarters. If the higher headquarters has authorized the use of protective obstacles in the ROE, tactical SOP, or OPORD, subordinate units are not required to submit a report of intention. Units establish SOPs for reporting initiation, progress, and completion of protective obstacles to the battalion level.
H-152. Individual units emplace and remove their own protective obstacles. Therefore, it is usually not necessary for the emplacing unit to turn over the obstacle to the overwatching force. If a nonorganic emplacing unit, such as an engineer platoon, emplaces the protective obstacle, the emplacing unit transfers the obstacle. Units mark protective minefields on all four sides. Units mark lanes and gaps according to ATTP 3-90.4. Commanders decide whether to mark other inherently dangerous obstacles based on the risk assessment. Protective munition fields are recorded using a +DD Form 3007 (Hasty Protective Row Minefield Record) as shown in figure H-20 (page H-48). Protective minefields are recorded using a scatterable minefield record. (Refer to JP 3-15 and ATP 3-34.20 for more information.)
Record)
H-153. Units also depict protective minefields and munition fields on their sector sketches. If the minefield or munition field is transferred to another unit, the transferring unit leader briefs the receiving unit leader and provides the necessary obstacle records. If the minefield or munition field is abandoned unexpectedly, the unit forwards the record to higher headquarters. (Refer to ATP 3-90.8 for more information on protective obstacles.)
