Manjuu airborne troops and government approval

How did Azur Lane's Royal Navy faction obtain approval for Manjuu airborne troops?

The need for government approval is disputed; no formal authorisation process is identified for the fictional Manjuu force.

The question applies a governmental approval model to Azur Lane's Manjuu airborne troops. The reply challenges the need for that approval and suggests the force simply exists within the setting. No story event or institutional rule is identified to explain its creation.
