The rank "Private" is changed to "Recruit", this is the first rank and it fits better with Recruit since "private" is the rank of a soldier. Recruits are not refered as soldiers just yet until they have proven that they belong in the liberation army of Flint Country.
Also I'd like to say welcome to our new recruit Akira Yamauchi to FLA. I know him from before and I dont think he will disappoint us.
