Random abilities
Name Description
Aggressive Attack Each of the unit’s attack values is increased by 2.
Aggressive Maneuver The unit’s movement factor is increased by 1.
All Weather Combat The air unit is not affected by weather conditions. Note: This can only be awarded air units.
Alpine Training When moving the unit treats forest and mountain hexes as clear terrain.
Note: Some units like e.g. german "Jaeger" infantry have this inherrent.
Battlefield Intelligence The unit cannot be surprised.
Bridging When moving the unit treats passable river hexes as rough terrain.
Combat Support The unit provides both Resilience and Skilled Ground Attack abilities to all adjoining units during combat phases. Will aid inflicting losses and save from loses by 2 to 3 points each battle.
Note: According to ingame tests, it seems that this works differently than stated in the readme.txt. Instead, working seems that Ground Units adjacent to Ground Units with Combat Support get for combat their expericne related bonuses calculated including the experience bars from the Combat Support unit. E.g., if fighting unit has 2 Experience Bars and Combat Support unit adjacent has 4 Experience Bars, the unit will fight like it would have 6 bars. For air units, it is the same, only that the Combat support unit has to be air unit as well.
Determined Defense Each of the unit’s defense factors is increased by 2.
Devastating Fire The unit may fire twice in a turn. Note: First shot is consuming the bonus (for this turn) but does not count as an attack otherwise - i.e. if the unit did not move, it can resupply after firing once!
Ferocious Defense The unit’s entrenchment cannot be ignored by enemy units.
Fire Discipline The unit will expend only one-half of an ammunition point each time it attacks.
First Strike The unit will fire first against an enemy unit if it wins the initiative in a combat round.

Influence Allows the unit to upgrade to better equipment at reduced prestige point cost.
Liberator You receive double the normal number of prestige points for all objective and victory hexes captured by the unit.
Overwatch The unit will fire at any enemy unit that moves within its range. The enemy unit is automatically surprised, allowing your unit to fire first and at the enemy’s close assault, rather than its ground defense, factor.
Overwhelming Attack When attacking the unit will have an indeterminate number of the suppression points it would otherwise inflict converted to kills.
Reconnaissance Movement The unit is permitted phased movement, just like reconnaissance units.
Resilience The unit will suffer 1 to 3 fewer step casualties than normal units when attacked.
Shock Tactics Any suppression which the unit inflicts on an enemy unit will last the entire player’s turn, not just the specific combat round.
