Communications is a temporary global Stat, which allows all of your 
Troops to use a number of active support 
Abilities.
Ways to Get Communications
- Specializing a
Comms. Officier (+5 , additional +1 with each new level). COs don't need to be deployed and boost communications indirectly, but once in the field they are anecdotally noted to use abilities more frequently than others. After a CO is dead, he no longer provides a boost. - Utilizing a Radio (+1 at a cost of taking an equipment slot).
Abilities Granted
- Solo Mission (noticeable Initiative boost for one trooper).
- Commando (not to be confused with Commando) (slight Initiative boost in an Area of Effect surrounding the trooper; hostile dummies caught in the AoE are affected as well).
- Locked (enemy target acquires the status, and is 100% likely to get hit).
- Propaganda (enemy trooper at very close range joins your side, completely retaining their current condition of life points, weapons, munitions, equipment, and effects), negated by Smart.
- Support (2 additional troopers Deploy during combat), comparable to Talky-Walky (1 trooper).
- Retreat (all friendlies exit the battle, being replaced by a fresh wave of reinforcements. Retreated troops join the next wave with life points, weapons, munitions, and equipment replenished, and no negative effects).
Bugs
- Commando will also affect enemy Rats caught in the Area of Effect.
