Explosive Ordnance Disposal (EOD)

Improvised Explosive Devices (IED)

  • ASOR uses a fictitious IED system and it does not reflect real world IED devices
  • IED is a explosive device generally home made used in the form of land mind type attacks. There are two main types of triggers for IEDs:
    • remote detonated
      • cell phone (yet to be implemented)
      • simple transmitter device (yet to be implemented)
    • victim detonated
      • pressure plate – completes circuit when stepped on
      • simple sensor – triggers when circuit broken generally infra red beam (yet to be implemented)
  • There a various types of IEDs this section will be updated as more types are introduced


  • ASOR uses an in house IED system called ARMAEdit-IED for its IEDs. This system has a two tier skill level for detection, interaction and disarmament of IED
    • High – EOD Engineer
    • Low – Regular Soldier
  • The IED System uses ACE interactions to interact with IEDs
  • An ACE Defuse Kit is also required to carry out most IED interactions
  • Some interactions can be done from the CROUCH position however others need to be done in PRONE, it is recommend all actions carried out on IEDs are done in PRONE
  • You need to get close and personal to the IED to see what your doing and be with in reach (less then 1m)

EOD Roles:

  • EOD Engineer
    • capable of performing all EOD functions at a high level
      • high level detection
      • high level exposing
      • high level defusing
    • duties include
      • vehicle repairs
      • explosive specialist
      • part of every red fire team and reports to FTL
      • primarily responsible for path clearing and ied detection together with setting and detonating friendly placed explosives 
      • placing information flags
      • wire cutting (only Arma 3 vanilla wire fences currently, by ACE interaction).
      • red team pointman and usually buddies with red FTL 


  • Path Clearing
    • when squads are moving around the EOD should be on point where practical clearing a path for the squad to follow
    • when in contact only do this when it is safe to do so, although you may have security to cover you while you clear this doesn’t make you bullet proof you are still responsible for your own safety
    • you have the option of placing GREEN flags in a cleared pathway 
  • Area Clearing
    • when squads move to an area and are stationary like a hill feature, compound, dead ground, behind rocks etc you need to be proactive in securing the area
    • don’t just search where you are now clear the whole area and likely paths or positions that friendlies might take or move to, it only takes a quick sweep around to ensure everyone is safe
    • you have the option of placing GREEN flags in the cleared area
  • IED Defusing
    • when attempting to defuse an IED you need to let your squad know and await the all clear
    • this gives them time to clear the area
    • there is no point just jumping in and attempting to defuse when your entire squad is standing in the blast radius 
    • notify your commander when the IED is defused
  • Vehicle Repair
    • although your primary role is EOD don’t forget you have the capability to repair damaged vehicles with the use of a toolkit. A toolkit is not required for changing tyres and requires the vehicle engine NOT to be running.


  • There is no difference between IED and IED Trigger detection
  • You have the option of placing a YELLOW flag in close proximity to explosives triggered by a pressure plate. This is because you are relatively safe, as it’s the pressure plate that is the danger.
  • You have the option of placing a RED flag in close proximity to the IED Trigger (pressure plate) or non pressure plate devices.
  • WHITE flags currently have no use. 
  • Metal Detection
    • ASOR Engineers use metal detectors to locate IEDs
    • they work on sound beeps for the user that increase in frequency when closer to the IED
    • they also detect mines
  • Visual Detection
    • all IEDs used by ASOR are visually detectable although some harder than others


    • Pressure Plate
      • can use the pressure plate to discover the location of the ied by tracing the buried wiring to the ied (ace action on pressure plate)
      • tracing the location of the ied spawns a small flag close to the location of the IED
      • pressure plates cannot be disarmed until the IED they are attached to has been disarmed (simple collapsing circuit)
    • Sensor
      • to be implemented
    • Remote
      • to be implemented
  • IED
    • There are three main parts to the disarmament of an IED
    • Exposing IED internals
    • Performing collapsible circuit bypass and neutralization
    • Removing of Detonator device
    • Once these steps are complete both the IED and Pressure plate can be dismantled safely

Vehicle-borne IED



  • In high IED threat areas squads will need to adapt their formations and tactics to compensate for EOD clearance of safe passages, IED finds and disarming.
  • SOP’s
    • The quickest way of negotiating a possible threat area is for the Engineer to sweep while the squad follow his path in strict column. This, of course, is the riskiest.  
    • The safest method is sending the engineer out on his own (with a buddy to cover him) while the squad stays back and then following his GREEN flagged marked path to safety.
    • Moving on cleared paths will not always be possible particularly in contacts or fast moving assaults
    • Since it takes TIME to detect and dispose of unexploded ordinance, the Squad Leader may have to take an alternate route if pressed for time.
    • When all else fails, a suspected area may be neutralized by the Engineer by placing demolition blocks and triggering from a safe distance.  
    • As the EOD you are the go to man on all things IED your squad leader may ask for your advice if you think a clearance is a good idea or not
    • when planning movement the likelihood of the presence of IEDs needs to be considered as it can completely alter the speed and maneuverability of your team
      • The threat of IEDs can be greatly reduced by educating yourself on commonly used tactics of the enemy.
      • Think about where you would put an IED for a force conducting what you are conducting against you.
      • Some likely positions are
        • bottlenecks in either roads or avenues of approach/retreat
        • dead ground 
        • defensive positions
        • assault staging positions
        • obvious routes or entry points to compounds
    • Compound Clearing Procedure
      • EOD will be required to take point on compound entries
        • ensure your buddy is ready to cover and is in place behind you
        • crouch and stay crouched, go prone on any contacts
        • peek and clear the doorway both for enemy and ied’s
        • let your buddy know your making entry
      • ON ENTRY
        • stay crouched so buddy can shoot over you if needed
        • clear the immediate area inside the doorway
        • if there is cover somewhere close to doorway move directly to it and clear it (building, wall, fence etc)
        • once inside of doorway is secure continue with standard compound clearance, ensure your buddy keeps you covered


The EOD Engineer role is extremely pro-active. It is also one of the most dangerous, as you are often pointman and most likely the first to take contacts from the front. Also you may not be successful in disarming a device, with obvious results. We are not saying go rogue and walk off on your squad clearing paths and areas but you need to be actively doing this beyond what you have been asked to do by your team leader. Try putting your weapon away occasionally and do your role, save some lives.
