Electronic Warfare[edit | edit source]

This guide explains how various aspects of Electronic Warfare work in RogueTech including Sensors, ECM, Probes and C3 Networks.

Key Concepts[edit | edit source]

Objectives[edit | edit source]

As a commander on the battlefield you want to use your electronic equipment to achieve following objectives:

  • Locate enemy units
  • Gain information about them
  • Protect your lance mates from enemy sensors

Electronic Warfare Checks[edit | edit source]

The core of the Electronic Warfare mechanics are the Electronic Warfare Checks (EWC):

  • A roll between -14 and +14
  • Normal distribution with 30% of the rolls above 0
  • Each check is modified by pilot skills and electronics equipment

There several EWC done during each round:

  1. EW efficiency check: EWC at the start of the round to identify overall EW efficiency.
  2. Sensor Range Check: EWC at the start of each combat round to identify sensor range.
  3. Sensor Check: a single EWC at the start of each combat round to identify level of details for all targets within range.

Example: We will use a Bushwacker equipped with AR14 Sheathed Beacon as an example through this guide.

Important notice: all sensor operations (checks etc) are individual to every unit, this means that some units in the same lance will have more information from sensors than the others.

Locating Enemy Units[edit | edit source]

In order to locate the target should be within Effective Sensor Range of our Bushwacker.

Effective Sensor Range is defined by three parameters:

  • Unit sensor range
  • EWC #2 which modifies unit sensor range every turn
  • Traget sensor signature

If the enemy unit is within Effective Sensor Range - you are able to get sensor info from it.

Unit Sensor Range[edit | edit source]

The table below contains base sensor range to locate each unit type.

Type Base Sensor Range
Mech 12 hexes * 30m = 360m
Vehicle 9 hexes * 30m = 270m
Turret 15 hexes * 30m = 450m
Others 6 hexes * 30m = 180m

Sensors range cannot drop below a number of hexes equal to SensorRangeMinimum. This value defaults to 6 hexes (240 meters).

Example: AR14 Sheathed Beacon provides +20% bonus to sensor range, which will allow our Bushwacker to locate enemy mechs at 360m * 1.2 = 432m or closer.

Modified Sensor Range[edit | edit source]

EWC #2 is rolled yielding a result between -14 and 14. The range check result is divided by ten, then used as a multiplier against the unit's sensor range. A range check result of +3 yields a sensor range multiplier of (1 + 3/10) = 1.3x. A negative range check of -2 would result in a multiplier of (1.0 - 2/10) = 0.8x.

Example: our Bushwacker has rolled +1 on the second EWC, this will result in a modified sensor range of 432m * 1.1 = 475m to detect enemy mechs.

Target Sensor Signature[edit | edit source]

Some of the enemy units have various equipment which reduces their sensor signature, making it harder to locate them. This equipment includes ECM, EWS and various stealth armours. The distance at which a target can be detected is defined as source sensor range multiplied by target signature.

Example: the target has Angel ECM which provides -15% to sensor signature. Our Bushwacker has modified sensor range of 475m, and it will be able to locate the target at 475m * 0.85 = 403m or closer. This is the Effective Sensor Range to locate the target.

Gaining Information: Sensor Check[edit | edit source]

Imagine that a target is within Effective Sensor Range (403m in our example), now we need to understand what information we can gain from the target. This is done through another Electronic Warfare Check (EWC #3). Ideally you want the roll to be as high as possible to obtain the most info from sensor contact.

Info Check Detail Level Details shown
< 0 No Info Failed sensor check, no information shown
0 Location Target location (3d arrow), but unknown name
1 Type As above, but type defined (mech/vehicle/turret)
2 Silhouette As above, with Chassis as name (Atlas, Catapult)
3 Vector As above, adding Evasion Pips
4 or 5 Surface Scan As above, adding Armor & Structure percentages, paperdoll
6 or 7 Surface Analysis As above, adding Weapon Types (as colored ???)
8 Weapon Analysis As above, with Weapon Names defined. Name is Chassis + Model (Atlas AS7-D, CPLT-C1)
9 Structure Analysis As above, plus current heat & stability, summary info (tonnage, jump jets, etc). Armor & structure includes current and max values. Name is Chassis + Variant name (Atlas ASS-HAT Foo, Catapult CPLT-C1 Bar)
10 Deep Scan As above plus component location, buffs and debuffs
11 Dental Records As above plus pilot name, info

Important notice: if the sensor check returns less than 0 - the sensors have failed a sensor check which is the same as if the target was outside of sensor range.
This also results in "+5 No sensor info" penalty when firing at a target.

Sensor Check Modifiers[edit | edit source]

We have covered all the key concepts and principles of Electronic Warfare and now we will take a look at what impacts sensor checks, how you can improve them for you and your lance mates and reduce them for the enemy units.

Sensor Check Modifiers
Postive Modifiers Negative Modifiers
Sensors

Active Probes

Tactics Skill

Target is within C3 aura

Unit is within C3M aura

Other buffs which improve sensor checks

Target has ECM/EWS equipment

Target is within enemy ECM aura

Unit is within Jamming aura of an enemy ECM

Example: our Bushwacker has AR14 Sheathed Beacon which provides +4 to sensor rolls, it's pilot has 5 in Tactics skill, which provides further +2 to sensor roll. Target Angel ECM provides -2 to sensor rolls against units with its aura.This totals to a +4 (+4 +2 - 2 = +4) to sensor check against the target. The result is that 70% of rolls will allow our Bushwacker lock onto the target identifying its location (will be equal or above 0) and 40% of the rolls will allow to see number of evasion pips (will be equal or above 3).

Overview of Electronic Warfare Equipment[edit | edit source]

There is a lot of equipment in RogueTech which is involved in the Electronic Warfare. Below is the short overview of different equipment types and its bonuses.

Equipment Type Typical Bonuses
Sensors
  • Increases Sensor Range by certain %
  • Sensor Strength: for each point of Sensor Strength unit gains +1 to sensor checks when gaining information about enemy units
ECM
  • ECM Shield: for each point of ECM Shield, attackers gain -1 penalty to sensors identification check. The color of the ECM Shield aura is Teal.
  • ECM Jamming: for each point of ECM Jamming on a target, the target suffers a -1 penalty to any sensors identification check they make. The color of the ECM Jamming aura is Blue.
  • ECCM: each point of ECCM reduces the strength of enemy ECM effects (Shield and Jamming) by 1. The color of the ECCM aura is Purple.
Active Probes
  • Increases Sensor Range by certain %
  • Probe Strength: each point of Probe Strength counters 1 point of ECM and Stealth effects
  • Sensor Check Strength: for each point of Sensor Strength unit gains +1 to sensor checks when gaining information about enemy units
Electronic Warfare Suites
  • Combine bonuses of ECM and Active Probes
  • Reduce radar signature
C3
  • For each point of Slave mitigates ECM/Stealth effects by 1 for ENEMIES within Green C3 aura.
  • For each point of Master improves sensor checks for ALLIED units within Green C3 aura.
  • Provides buffs to ALLIED units within  Orange Buff aura.
Stealth Armour
  • Reduces sensor signature of a unit
  • Provides additional reduction in signature and penalties to sensor checks for each of the stealth charges

Electronic Warfare Examples[edit | edit source]

Active Probe Examples[edit | edit source]

Example 1 - with ECM:

Ative probe.png

  • Unit F carries a Beagle Active probe which has 2 Probe Strength and 2 Checks Strength.
  • An enemy Unit B is covered by Guardian ECM which provides 3 ECM Shield effect.
  • Probe Strength effect of will reduce strength of Enemy ECM Shield effect by resulting in net 1 point of ECM Shield protection (-1 to sensor checks against this unit).
  • Since Unit F has Check Strength 2, it will result in net +1 to Sensor Checks against the target (-1 from ECM Shield and +2 from Check Strength).
  • Unit E does not benefit from Beagle Active probe effects.

Example 2 - no ECM:

  • Our unit carries a Beagle Active probe which has 2 Probe Strength and 2 Checks Strength.
  • An enemy unit is not covered by ECM or any other EW equipment.
  • Probe Strength of our unit does not matter since this parameter specifically mitigates ECM.
  • Since our unit has Check Strength 2, it will result in net +2 to Sensor Checks against the target .

ECM Examples[edit | edit source]

On diagram 2 we have 5 units:

  • Units A, B and C in Blue team, with Unit A carrying a Guardian ECM in ECM mode
  • Units D, E in Orange team

ECM diagram-0.jpg

C3 Examples[edit | edit source]

C3.png[edit | edit source]

  • Unit A carries a Guardian ECM, which provides ECM Shield effect for Unit B of strength 3.
  • Unit F carries a C3 Slave, which mitigates ECM and Stealth effects within Aura by 1.
  • The ECM Shield effect on Unit B is reduced by 1 (from 3 to 2) both for Unit F AND Unit E, since Unit B is within the C3 Aura of Unit F.

Stealth Example[edit | edit source]

  • Unit A carries Stealth Armour and has all it's stealth (3) charges:
    • It has 66% signature reduction (-15% flat signature reduction and 60% signature reduction from its charges).
    • It is harder to hit by 2/2/3 at Medium/Long/Extreme distances
    • It has 15% visibility reduction
  • Unit B is equipped with a Beagle Active Probe which has a Probe power of 2 (mitigates ECM and Stealth effects by 2):
    • For Unit B, Unit A has 32% signature reduction (2 of the stealth charges are mitigated)
    • Also for Unit B, Unit A will have its ECM Shield reduced by 2 (It needs to carry some type of ECM to equip Stealth armour)
    • Other units will gain no benefit from the Unit B Beagle Active Probe
