Capable of being dragoon-conscripted or pressed into military service; subject to forced military recruitment.
From 'dragoon' (mounted soldier, from French 'dragon') + '-able' (capable of). Dragoons were soldiers who forcibly conscripted or coerced people.
The ability to add '-able' to almost any verb is one of English's superpowers—it transforms action into possibility, so a 'dragoonable' person is one the military could legally force into service, which was actually a real legal category in history!
