National Guard Act, or equivalent?

In the US, the National Guards belong to the states, until the Federal government comes calling, but are trained to Federal (regular Army or Air Force) standards, with standard equipment and uniforms and so on.<br /><br />I'm not saying the planetary militias should have the same relationship to UPF SpaceFleet, but what is their relationship, if any? These can be questions to ask.<br /><br />Is there a legal framework for a UPF commander to take operational control of militia vessels in case of Sathar invasion? (my slipshod reading: no?)<br /><br />Do some or all of the militias try to live up to UPF standards of training and professionalism? (I think Clarion certainly does-- of course, if you ask them, UPF only tries to live up to <b>Their </b>standards!) Have they got similar enough jargon that they don't have difficulty communicating (like a metric vs. English problem)?<br /><br />Do they buy the same ships from the same shipyards, or do they buy cast-off UPF ships? (the popularity of the Assault Scout indicates some similarities) <br /><br />What about other equipment--are the sensors and radio equipment and the like standard, so that parts might be swapped? I would assume that most comms are similar enough that they can use voice comms, but can their computers speak to each other on a meaningful level-- can they share tactical data and guide each other's weapons? If someone bought their ships and tactical computers from Streel, can they share data with a PGC-built network?<br /><br />For that matter, who buys their ships from one shipyard, but later upgrades the engines from somewhere else, then 10 years later, adds on weapons and guidance package from Source C, and so on? I'm thinking of the Israeli Sherman tanks-- American-built, but later added French guns and someone else's engines, and who knows what other components from somewhere else. Sooner or later, that kind of mix &amp; match stuff might come back to bite someone!
