So, I've been thinking of certain things/concepts about my military OCs:
1. Cycles between representations
2. Representations and military districts
3. Resigning military representations
4. Global military representation councils
I've been thinking that maybe there may be a cycle that occurs whenever a representation may die or resign. This cycle will either happen one of two ways, hierarchically or democratically. The first is along the lines of Chain of Command, where the representation's XO (usually the representation of a military region or military organization) takes the place. The latter is along the lines of who do the other reps within that nation's military want to instill as the new international representation.For example, Captain Yuri Ivanov (My Novorossiya Armed Forces OC), once the Ukrainian Ground Forces, was replaced by one of his peers, another military district representative within Ukraine.
I believe that most of the representations of the international militaries also represent something else besides the nation's military. They may also represent something cultural or other military units. For example, Captain Nikolai Ivanov is not only the representation of the Russian Ground Forces, but also the Western Military District of the Russian Federation, the 5th Guards Tamanskaya Motor Rifles Brigade, and the Kuban Cossack Host.
I believe that the representations can resign at any time or by old age. Many of the older representations were obviously the militaries of their nations until either a new government or a new nation took it's place (such as the replacement of the Druzhina of the lands of Kievan Rus' to the Landed Army of the early Russian Empire). I also think that maybe, if cooperation within a nation's armed forces and in the international sphere due to personal belief, that a representation may resign as well.
Much like the nations, I believe that a couple times in a year, the armed forces of the world come together for conferences and summits to discuss current events, possible plans of action, and even combat readiness training among attendees. However, there are other pact councils that may be in place that members of those pacts can attend (i.e. NATO, SEATO, BRIC, CIS, EU, etc...).
