Umm… can a naval battle have “fighting terrain”? I need a subhead and “fighting terrain” seems more idiomatic than “fighting water,” but the use of a land-based word for maritime combat has me hesitating. Thoughts? #indexing #indexodon #AmIndexing #FunWithEtymology

PS. I really want to say “fighting merain,” but I know better. And it sounds too much like (sheep) murrain, which prompts some interesting visuals.
