Probably my least favorite of all RPC tropes is the notion that protection, security, and operational staff would follow traditional military conventions, particularly military grade that exactly corresponds with US Army grades.
Whenever I see military grade used in any piece on this wiki, the grade virtually always appears to be arbitrarily or randomly selected, and in a way that suggests that the author has little familiarity with the purpose of specific military grades, their historical development, their roles within real life militaries, nor have they given much thought to how those roles would translate to an organization like the Authority (on this hub, for example, why has a random Chief Warrant Officer been given the task of greeting all new recruits. Not saying a warrant officer would never be given such a task in a real military, but it seems an odd choice, especially given how the actual functions of warrant officer grades vary greatly among different military branches and among different nations. Wouldn't an O-6 or above make more sense?)
One thing noticeably lacking from these documents is an explanation of how these personnel are recruited from the general public. Real life military rank systems are designed for a world in which we recruit 18 year olds right out of K-12 schooling en masse to train their capabilities from the ground up, with some being selected for officer training.
Would such a recruiting model make sense for the Authority? It's not like the Protection Division can have recruiting offices in every city and send recruiters out to high school career fairs. I would think recruiting would be more along the lines of hand-picking highly qualified individuals who already have a high amount of military or paramilitary experience. Sending them all to a glorified boot camp of the kind designed for teenage army recruits wouldn't make much sense.
Use of low-end grades like "corporal" or "second lieutenant" is especially annoying, because it suggests that the Authority either routinely keeps around personnel with no previous qualifications or merits beyond baseline recruit or officer training, or that they recruit people with advanced qualifications that translate to advanced grade in the real world and make them all start their Authority careers as lowly privates and butter bars. It doesn't make the Authority look very competent in terms of managing and incentivizing a human resources pool.
Beyond such minutia, this whole division hub is little more than a pointless info dump with little to make it inherently interesting. Do we really need to know how long recruit training is or what the different training phases are? Beyond the scant references to anomalies, all this really does is describe the mundane functions of what a military does.
