ANBU squads and Promotion prerequisites

[Chigokai Yuna]

Upon Yuna gaining the ANBU Sennin rank multiple changes were made, the biggest ones regarded the ANBU branch as a whole.
She decided to make a whole clean slate and to keep things generally simple by having 3 sub branches.
These Sub branches are:
Assassins
Diplomats
Intel

The Sub branches will be available for each ANBU and higher ranked individuals to choose from.
AIT will work with all three sub branches loosely as they figure out what serves them best and will choose upon graduation to ANBU rank
The leaders of these Sub branches will be at minimum ANBU Captains.
That being said, since there are only 3 positions, it doesn't entirely mean that the branch will only have 3 Captains but rather those three will be the leaders of the Sub branches.

Before going too deep into it, lets talk about promotion requirements.
AIT to ANBU
Either fulfill 3 intermediate type missions (Solo modded missions, not self modded), Complete a slightly harder mission (team modded mission), or participate in a challenging mission (most events and A rank missions)
ANBU to ANBU Captain
As above, but also must participate in a modded combat, stopped a forced entry, exit, or missing attempt
ANBU Captain to leader of Sub branch
Complete sub branch specific type missions (mainly ones that have big impacts on Cloud for the better)

Exams will be given out to those who meet these requirements, and as one doesn't need all to help push for a promotion, it will certainly help build a merit for your character to be more known throughout the ANBU Branch.
The Leaders of the Sub branches are:
Assassins:
Diplomats: Orochi Sakura
Intel: Hyuuga Honnou​

So you know the names of these Sub branches, but other than stating the obvious, you don't know about their mechanics and how they work. So let's get into it, shall we?

Assassins: These people of the ANBU Branch will hold the BINGO Book closer to them than all other shinobi, even that of other ANBU Agents. The operatives in this branch are excelled in fighting both domestic (mainly mission or event enemies) to foreign threats (missing and mercenary mainly). While it isn't necessary that the agents of this sub branch are well versed in the battle system, it is encouraged as they will be the ones to be expected to go out on the most dangerous of missions.

Diplomats: Power and killing isn't everything when it comes to the ANBU. The Diplomat Sub branch are expected to have some charisma and high problem solving skills in order to think more than just the Village, but rather multiple nations as a whole. Their job is to help bring peace between the nations when things such as false accusations are thrown about one way or another from either nation. These people hold the most power and should be picked very carefully and cautiously, and their thought process must be higher than that of a single Village but that of multiple.

Intel: Knowledge is power. And most wars are won before they are even fought simply because of how strategically placed ones soldiers are. The agents of this Sub branch must focus on gathering information both inside and outside Lightning Country. It is through their job that it can help the Assassins learn about their targets and their targets location. Whilst inside Lightning Country, they will act as a deterrent by looking and listening for potential threats that are in the Country. Agents of Intel's fist job of finding something out is to inform. Only step in and act if necessary for the safety of Cloud.
