Leadership (Skirmishers)
URL Copied!

While skirmishing troops are scattered across a broad front their leader may not be able to see all his troops, while individual warriors may be unaware of what is happening to the unit as a whole. This is one of the disadvantages of skirmishing: troops are unable to benefit from the presence of standards or potent leaders, separated as they are by distance and cover. To represent this a skirmishing unit always tests its leadership on the leadership value of the troops even if they are accompanied by a leader with a higher leadership value. Even the leader tests on the lower value. In addition, skirmishers cannot test on the army general's leadership and do not benefit from battle standard re-rolls as do other troops. This means that skirmishing troops are bound to be more fragile than properly formed troops in combat, and if beaten they will be more likely to break and flee.
