6 Air Defense (Mechanized Veteran): The air defense unit can fire after making its move.
7 Fighter (Skilled Interceptor): The unit can intercept multiple enemy aircraft in the defensive phase.
8 Tactical Bomber (Skilled Assault): The unit cannot be surprised ("out of the sun") in combat.

All Weather Combat (awarded only to air units): The unit's attack capability is not affected by adverse weather conditions.
Alpine Training: When moving, the unit treats forest and mountain hexes as clear terrain.
Battlefield Intelligence: The unit cannot be surprised in combat. This is most effective against enemy tanks with an overwatch leader trait.
32 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.
Determined Defense: Each of the unit's defense factors is increased by 2.
Devastating Fire: The unit may fire twice in 1 turn.
29 Ferocious Defense: The unit's entrenchment cannot be ignored by enemy pionieres or engineers.
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.
Forest Camouflage: If in a forest hex, the unit cannot be spotted by enemy units unless they move adjacent to it; a rarely seen leader trait.
21 Infiltration Tactics: The unit ignores enemy unit entrenchment when calculating combat results. It also serves as a bridging unit, which allows other units to cross passable rivers.
Influence: The unit can upgrade to better equipment at a reduced prestige point cost.
Liberator: The player receives twice the normal amount of prestige points for any objective or victory hex it captures.
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. Note: a unit with an Overwatch leader will only fire at the first enemy unit that comes within range, not any subsequent enemy units.
26 Overwhelming Attack: When attacking, the unit will have an indeterminate number of the suppression points it would otherwise inflict converted to kills.
23 Reconnaissance Movement: The unit is permitted phased movements, 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. This is most effective with artillery units. Assuming there are two enemy artillery units, if a shock tactics leader fires upon one of the enemy artillery units, that unit will not fire defensively for the rest of the turn. So, intead of two artillery units firing defensively, there will only be one to contend with for that turn.
24 Skilled Ground Attack: The unit will inflict 1 to 3 more step casualties than normal units when attacking.
Skilled Reconnaissance: The unit's spotting range is increased by one hex. If a recon unit receives two skilled reconnaisance traits, the total spotting range will double.

Superior Maneuver: The unit ignores enemy units' zones of control.
Tenacious Defense: The unit's ground defense factor is increased by 4.
