Module Functional.Suppression
Functional - Suppress fire of ground units when they get hit.
Features:
- Hold fire of attacked units when being fired upon.
- Retreat to a user defined zone.
- Fall back on hits.
- Take cover on hits.
- Gaussian distribution of suppression time.
Missions:
MOOSE - ALL Demo Missions
When ground units get hit by (suppressive) enemy fire, they will not be able to shoot back for a certain amount of time.
The implementation is based on an idea and script by MBot. See the DCS forum threat for details.
In addition to suppressing the fire, conditions can be specified, which let the group retreat to a defined zone, move away from the attacker or hide at a nearby scenery object.

Mimic suppressive enemy fire and let groups flee or retreat.
Suppression Process
The suppression process can be described as follows.
CombatReady
A group starts in the state CombatReady. In this state the group is ready to fight. The ROE is set to either "Weapon Free" or "Return Fire". The alarm state is set to either "Auto" or "Red".
Event Hit
The most important event in this scenario is the Hit event. This is an event of the FSM and triggered by the DCS event hit.
Suppressed
After the Hit event the group changes its state to Suppressed. Technically, the ROE of the group is changed to "Weapon Hold". The suppression of the group will last a certain amount of time. It is randomized an will vary each time the group is hit. The expected suppression time is set to 15 seconds by default. But the actual value is sampled from a Gaussian distribution.
The graph shows the distribution of suppression times if a group would be hit 100,000 times. As can be seen, on most hits the group gets suppressed for around 15 seconds. Other values are also possible but they become less likely the further away from the "expected" suppression time they are. Minimal and maximal suppression times can also be specified. By default these are set to 5 and 25 seconds, respectively. This can also be seen in the graph because the tails of the Gaussian distribution are cut off at these values.
Event Recovered
After the suppression time is over, the event Recovered is initiated and the group becomes CombatReady again. The ROE of the group will be set to "Weapon Free".
Of course, it can also happen that a group is hit again while it is still suppressed. In that case a new random suppression time is calculated. If the new suppression time is longer than the remaining suppression of the previous hit, then the group recovers when the suppression time of the last hit has passed. If the new suppression time is shorter than the remaining suppression, the group will recover after the longer time of the first suppression has passed.
For example:
- A group gets hit the first time and is suppressed for - let's say - 15 seconds.
- After 10 seconds, i.e. when 5 seconds of the old suppression are left, the group gets hit a again.
- A new suppression time is calculated which can be smaller or larger than the remaining 5 seconds.
- If the new suppression time is smaller, e.g. three seconds, than five seconds, the group will recover after the 5 remaining seconds of the first suppression have passed.
- If the new suppression time is longer than last suppression time, e.g. 10 seconds, then the group will recover after the 10 seconds of the new hit have passed.
Generally speaking, the suppression times are not just added on top of each other. Because this could easily lead to the situation that a group never becomes CombatReady again before it gets destroyed.
The mission designer can capture the event Recovered by the function SUPPRESSION.OnAfterRecovered().
Flee Events and States
Apart from being suppressed the groups can also flee from the enemy under certain conditions.
Event Retreat
The first option is a retreat. This can be enabled by setting a retreat zone, i.e. a trigger zone defined in the mission editor.
If the group takes a certain amount of damage, the event Retreat will be called and the group will start to move to the retreat zone. The group will be in the state Retreating, which means that its ROE is set to "Weapon Hold" and the alarm state is set to "Green". Setting the alarm state to green is necessary to enable the group to move under fire.
When the group has reached the retreat zone, the event Retreated is triggered and the state will change to Retreated (note that both the event and the state of the same name in this case). ROE and alarm state are set to "Return Fire" and "Auto", respectively. The group will stay in the retreat zone and not actively participate in the combat any more.
If no option retreat zone has been specified, the option retreat is not available.
The mission designer can capture the events Retreat and Retreated by the functions SUPPRESSION.OnAfterRetreat() and SUPPRESSION.OnAfterRetreated().
Fallback
If a group is attacked by another ground group, it has the option to fall back, i.e. move away from the enemy. The probability of the event FallBack to happen depends on the damage of the group that was hit. The more a group gets damaged, the more likely FallBack event becomes.
If the group enters the state FallingBack it will move 100 meters in the opposite direction of the attacking unit. ROE and alarmstate are set to "Weapon Hold" and "Green", respectively.
At the fallback point the group will wait for 60 seconds before it resumes its normal mission.
The mission designer can capture the event FallBack by the function SUPPRESSION.OnAfterFallBack().
TakeCover
If a group is hit by either another ground or air unit, it has the option to "take cover" or "hide". This means that the group will move to a random scenery object in it vicinity.
Analogously to the fall back case, the probability of a TakeCover event to occur, depends on the damage of the group. The more a group is damaged, the more likely it becomes that a group takes cover.
When a TakeCover event occurs an area with a radius of 300 meters around the hit group is searched for an arbitrary scenery object. If at least one scenery object is found, the group will move there. One it has reached its "hideout", it will wait there for two minutes before it resumes its normal mission.
If more than one scenery object is found, the group will move to a random one. If no scenery object is near the group the TakeCover event is rejected and the group will not move.
The mission designer can capture the event TakeCover by the function SUPPRESSION.OnAfterTakeCover().
Choice of FallBack or TakeCover if both are enabled?
If both FallBack and TakeCover events are enabled by the functions SUPPRESSION.Fallback() and SUPPRESSION.Takecover() the algorithm does the following:
- If the attacking unit is a ground unit, then the FallBack event is executed.
- Otherwise, i.e. if the attacker is not a ground unit, then the TakeCover event is triggered.
FightBack
When a group leaves the states TakingCover or FallingBack the event FightBack is triggered. This changes the ROE and the alarm state back to their default values.
The mission designer can capture the event FightBack by the function SUPPRESSION.OnAfterFightBack()
Examples
Simple Suppression
This example shows the basic steps to use suppressive fire for a group.
Customization and Fine Tuning
The following user functions can be used to change the default values
- SUPPRESSION.SetSuppressionTime() can be used to set the time a goup gets suppressed.
- SUPPRESSION.SetRetreatZone() sets the retreat zone and enables the possiblity for the group to retreat.
- SUPPRESSION.SetFallbackDistance() sets a value how far the unit moves away from the attacker after the fallback event.
- SUPPRESSION.SetFallbackWait() sets the time after which the group resumes its mission after a FallBack event.
- SUPPRESSION.SetTakecoverWait() sets the time after which the group resumes its mission after a TakeCover event.
- SUPPRESSION.SetTakecoverRange() sets the radius in which hideouts are searched.
- SUPPRESSION.SetTakecoverPlace() explicitly sets the place where the group will run at a TakeCover event.
- SUPPRESSION.SetMinimumFleeProbability() sets the minimum probability that a group flees (FallBack or TakeCover) after a hit. Note taht the probability increases with damage.
- SUPPRESSION.SetMaximumFleeProbability() sets the maximum probability that a group flees (FallBack or TakeCover) after a hit. Default is 90%.
- SUPPRESSION.SetRetreatDamage() sets the damage a group/unit can take before it is ordered to retreat.
- SUPPRESSION.SetRetreatWait() sets the time a group waits in the retreat zone after a retreat.
- SUPPRESSION.SetDefaultAlarmState() sets the alarm state a group gets after it becomes CombatReady again.
- SUPPRESSION.SetDefaultROE() set the rules of engagement a group gets after it becomes CombatReady again.
- SUPPRESSION.FlareOn() is mainly for debugging. A flare is fired when a unit is hit, gets suppressed, recovers, dies.
- SUPPRESSION.SmokeOn() is mainly for debugging. Puts smoke on retreat zone, hideouts etc.
- SUPPRESSION.MenuON() is mainly for debugging. Activates a radio menu item where certain functions like retreat etc. can be triggered manually.
