NOTE: Below, by ranks, we mean actual positions, like an example would be lieutenant, we don't mean your threat level, this only applies to those who want to be Ninja Guardians.
The Guard Captain: This is the greatest rank you can have amongst the 2-4 man squad of guardians. This personm leads that individual guardian squad during missions, when sent out by a feudal lord.
Senior Blade: A Senior Blade serves as the highest rank, that is not official for men of that squad. Senior Blades, had been given that name, due to their mass of experience, that is what it primarily shows.
Country Guard: A country guard is the average rank amongst Guardians throughout the Naruto World. You have respect, and still need to show potential for a greater rank.
Polished Blade: A Polished Blade is another term for a "noob" within the Ninja Guardians. All Guardians MUST start out as a polished blade, unless given special and official permission NOT TO by staff.
END NOTE: Note that there are only 4 ranks, well the maximum amount of Ninja Guardians per a Daimyo/Feudal Lord are only 4. Please be aware of this.
