Thanks ... on the board: Defence INF: +2 when you look at woods. Am I not right?
Can already finished units assit?
The Terrain table, both on the map and in the rulebook, shows Defence / Woods / INF / +1. Urban is the only terrain type that provides infantry with +2DV.
Finished units cannot do anything, assisting included, until the end of the turn or their next activation, whichever comes first.
