Vojno could be one of 2 things: 1. The noun "vojna" which means war in the 4th or 6th grammatical case, which is "vojno". 2. The adjective "vojen" which means "pertaining to war", which becomes "vojno" when describing a neuter gender noun. I think "vorjen" doesn't mean anything. I also can't find it in the dictionary.

military in orthodox languages means war end it can also mean preparing for war.

"vorjen" could be a misspelling of "vrojen", which means inherent/congenital (similar to the more common "prirojen", but "vrojen" stresses the embeddedness).
