In addition to other comments, Bash is a "standard orc" with unofficial ranking. He's a regular green orc with no distinguishing features as far as orc classifications go. His equipment just looks like a normal stuff to anyone who hasn't been hit by it. All of his honest statements about his status sounds the same as regular orc boasting. Zell's testimony means nothing, to anyone who doesn't already know her, because fairies lie.
As the humans in the first arc mentioned, all other orcs outside of orc lands are wild orcs who have disobeyed the king and are considered traitors to their kind and the treaties: to be killed on sight.
Bash is the only orc with legal permission to be in foreign lands in which only the survivors/war heroes would personally recognize him. So far only one has appeared, but there will be more.
