093-401-5040 (SL1) - React to Unexploded Ordnance Hazards

Standards: Identified UXO by type and subgroup; recognized associated hazards; took immediate action to prevent death, injury, or damage to materiel; reported the UXO hazard using the UXO Spot Report format.

Conditions: In a field environment, given an item(s) of simulated unexploded ordnance (UXO), marking materials, and a UXO Spot Report format.

Standards: Identified UXO by type and subgroup; recognized associated hazards; took immediate action to prevent death, injury, or damage to materiel; reported the UXO hazard using the UXO Spot Report format.

Performance Steps

1.   Recognize the UXO hazard.


Never approach a UXO once it has been identified.  Approaching UXO may cause them to explode.



Never strike, jar, or touch a UXO.  Do not move or remove anything on or near a suspect UXO.  UXO can be extremely sensitive and can cause serious injury or death if disturbed in any way.



Many types of UXO may contain an incendiary (fire producing), chemical, biological, or radiological hazard in addition to explosives.



Do not make radio transmissions within 100 meters of a UXO.  Some types of UXO are sensitive to electromagnetic radiation (EMR) and may explode.

a. Identify the four types and subgroups of UXO.

(1)  Dropped.

 (a) Bombs (figure 093-401-5040-1):

-Vary from 3 to 6 feet in length.

-Vary in diameter from 5 to 36 inches.

-Often have a sloped or "bullet" shaped nose, fins and/or a parachute on the back.

-May contain high explosive, incendiary, or chemical fillers.

(b) Dispensers (figure 093-401-5040-2):

-Contain numerous submunitions or bomblets.

-Most have the same characteristics of bombs.

-May be found intact or partially open.

Figure 093-401-5040-2. Dispensers


(c)   Submunitions (figures 093-401-5040-3a through 093-401-5040-3e):


When a submunition is identified, leave the area by the same path you entered.  There may be many more submunitions in the same area. Small size does not diminish the danger of submunitions. The smallest can easily injure or kill.

-May contain the same hazards of bombs (explosive, chemical, biological, radiological, incendiary). 

-Are designed to be scattered over a wide area.

-Come in many shapes and sizes; may or may not be "bullet" shaped.

-May look like balls, wedges, or cylinders.

-May have fins, ribbons, parachutes, or trip wires.

(2)  Projected.

(a)   Projectiles (figures 093-401-5040-4a through 093-401-5040-4b):

-Include munitions from large machine guns, artillery howitzers, and naval guns.

-Range in size from 20mm up to 16 inches in diameter; 10 to 30 inches in length.

-Most resemble a "bullet" shape.

-Can contain explosive, chemical, biological, radiological, and/or incendiary hazards.

(b)   Mortars (figures 093-401-5040-5a through 093-401-5040-5b):

-Most have fins and a "bullet" shape.

-Range in size from 60mm to 120mm in diameter; 12 inches to 36 inches in length.

-Can contain explosive, chemical, or incendiary hazards.

(c) Rockets (figures 093-401-5040-6a through 093-401-5040-6c):

-May or may not have fins.

-Have some sort of rocket motor vents in back.

-Range in length from 24 inches to several feet.

-Can contain explosive, chemical, or incendiary hazards.

Figure 093-401-5040-6a.

(d)   Guided Missiles (figure 093-401-5040-7a through 093-401-5040-7b):

-Most have fins.

-Some have wires in the end for guidance.

-Very similar to rockets.

-Can contain explosive or incendiary hazards.

Figure 093-401-5040-7a.


Figure 093-401-5040-7b.

(e)   Rifle Grenades (figures 093-401-5040-8a through 093-401-5040-8b):

-Designed to be fired from rifles or shoulder fired launchers.

-Resemble rockets but are smaller.

-Can contain explosive or incendiary hazards.

Figure 093-401-5040-8a.

(3)  Thrown (figures 093-401-5040-9a through 093-401-5040-9b):

-Includes all types of grenades, including simulators.

-Most are round or cylindrical.

-Are small enough to be thrown by a person.

-Can contain explosive or incendiary hazards.

-Dud simulators require the same safety procedures as other ordnance.

Figure 093-401-5040-9a.


Figure 093-401-5040-9b.



Never approach a grenade that was thrown and did not detonate, even if you threw it.  Do not move, jar, or disturb-the fuse may function at any time.

Never pick up, move, or disturb a found grenade, even if spoon or safety pin are attached.  The grenade may be booby-trapped and explode when disturbed.

(4)  Placed (figures 093-401-5040-10a through 093-401-5040-10b):

-Includes all land or sea mines.

-Range in size from 2 inches in diameter to several feet in length.

-Have a variety of fuse types; pressure plates, tilt rods, trip wires, electronic sensors, or command detonated.

-Can contain explosive, incendiary, or chemical hazards.

Figure 093-401-5040-10a.


Figure 093-401-5040-10b.



Consider all mines to be booby-trapped or to have anti-disturbance fusing.   Never attempt to uncover or remove placed ordnance.



2.   React to the UXO hazard.

a. Do not touch or disturb the UXO or any wires, parachutes, or anything attached or surrounding the UXO.  Do not move closer to UXO.

b. If any peculiar smells, liquids, or dead animals are present, chemical or biological agents may be present; don mask and MOPP gear immediately.

c. Mark location with material such as white engineer tape, marking ribbon, clothing, or sign.  Place marker above ground at waist level if possible.  Take note of physical terrain features of location and route back to UXO so EOD team can return and dispose of UXO.

d. Evacuate personnel and equipment from area surrounding the UXO:

(1)  Bombs, dispensers, large projected munitions (90-mm diameter and larger)-evacuate a 360-degree perimeter at least 600 meters.

(2)  Submunitions, placed, thrown, small projected munitions (smaller than 90-mm diameter)-evacuate a 360-degree perimeter at least 300 meters.

e. If personnel or equipment cannot be evacuated, seek as much frontal and overhead cover as possible.

f.  If UXO is suspected to have a chemical agent, ensure all personnel stay upwind of item and are in full MOPP.

3.   Report the UXO hazard.

a. Report UXO hazard to your chain of command.  You or your chain of command should request Explosive Ordnance Disposal (EOD) support using the nine-line UXO Spot Report:

(1)  Date and time of the fall, impact, or finding of the UXO item(s).

(2)  The exact location of item(s) including grid coordinate, landmarks, reference points, or street addresses.

(3)  The name and organization of person reporting the incident including call sign or phone number.

(4)  Identify UXO by type (Dropped, Projected, Thrown, Placed) and subgroup.

(5)  Any NBC contamination present.

(6)  What resources are threatened?

(7)  How the UXO has affected unit mission.

(8)  The safety measures that have been taken including the evacuation distances that have been accomplished.

(9)  The requested priority for receiving EOD support (Immediate, Indirect, Minor, No Threat)

b. Be prepared to provide a guide to the EOD team.

Evaluation Preparation: 

Setup:  Do not evaluate this task using live UXO.  Utilize training items from your installation Training Aids Support Center.  Preliminary instruction of this task can be obtained by requesting support from nearest Army EOD company.  Evaluate this task during any training exercise where UXO is likely to be encountered.  Place UXO training aid near personnel, facilities, or equipment within the soldier's area of responsibility.  Soldier should identify UXO from at least 5-10 meters away or through the use of binoculars.

Brief Soldier:  Tell the soldier he will be evaluated on his ability to properly recognize, react to, and report a UXO hazard.  The soldier will identify the UXO by type and subgroup, take appropriate actions to react to the hazards, and report the hazard using the nine-line UXO Spot Report format. 

Performance Measures



1.   Identified UXO by type and subgroup.



2.   Reacted to UXO hazard, observing all applicable safety precautions.



3.   Marked the UXO.



4.   Determined appropriate evacuation distance (Large item: 600m; Small item: 300m).



5.   Reported UXO hazard using the nine-line UXO Spot Report.



Evaluation Guidance:  Score the soldier GO if all performance measures are performed correctly.  Score the soldier NO GO if any performance measure is not performed correctly.  If the soldier scores NO GO, show him what was done wrong and how to do it correctly.
