The Rules Team, with Design input, has made the following change to the Naval ability.
Reaction: If you are the Attacker and your current army has more Naval cards than the opposing army, once per battle after engaging, target your Naval Personality: You have the first opportunity to take a Battle action, which must be performed by the targeted Personality or one of his Naval Followers.
This is reflected in the various places in the Comprehensive Rules.
The primary effect of this is to change how this ability interacts with cards that allow changing targets, notably Misdirection.
