Sneak Attack

The army increases its OM by 1 when making an ambush, when using the expert flankers tactic, or on the phase after using the false retreat tactic. The
army can also use this ability in conjunction with
the Pincer Maneuver Tactic and the Wolves in
the Fold Command Boon. In addition, on a successful attack when using this ability, the
attack deals an additional +1 point of damage for
every 2 levels of the ninjas or rogues in the army
over 1st.
