Effects of Experience Points

Source: Core Rulebook 3E, p. 161

For every 1,000 experience points a unit earns it gains a Battle Honour, rolled for on the appropriate table; losing experience can cause a Battle Honour to be lost again.

As a unit gains or loses experience and its status changes, it will gain certain benefits or suffer penalties. For every 1,000 experience points a unit earns, it gains a Battle Honour. Each Battle Honour is represented by a particular skill or ability, depending upon the type of unit. For every Battle Honour a unit gains, make one D6 roll on the appropriate Battle Honours table (infantry, bike/cavalry and vehicle tables are given later on). If you roll a Battle Honour the unit has already you can choose one of the other Battle Honours on the list instead.

If a unit loses a Battle Honour due to its experience being reduced, randomly determine which one is lost.
