I've installed 6.4 but feel archers are too lethal: is Real Combat included 6.4? No right? Only Real Recruitment? Advices plz...

SSHIP features look exactly perfect for polishing the SS campaign (from my perspective) But it is not compatible with other submods. However, Real Recruitment is already enabled via the SS setup, so, installing SSHIP will be in addition to Real Recruitment, right?
