From a Help / Support (aka Ask A Question) ticket ...

e.g.

Hello. Re: Scout Hero Skills: Does Army Offense / Defense / Health and/or Reduced Enemy Defense / Offense / Health (or any other non-Raid non-'Scout' 'Skill') affect Scout stats, and where are they shown in Palace / Statistics? Thanks.

These Hero Skills affect all troops including the Scout type troops. You can find the bonus given from this Skill in the Palace → Statistics → Army → Warriors.

If you've ever wondered if some things don't apply to scouts, since they're presented differently ...
