It's interesting that the Traveller model is not 'apply to a bunch of schools or find a job in essential areas or else get drafted'. Instead, it is 'try getting a job somewhere, and when you blow the first one... the government steals you!'. <rolls eyes>

To those of us in the USA who grew up w/ 'the draft' in the US (like MM) it seems not out-of-the-ordinary.
But for the ImpGov? Not so much.
But, I could see local govs, depending upon gov-class, 'impressing' folks & maybe even sending out the good old 'press gangs'.
Or, as I heard in an old movie, "You all now compulsorily enlisted!".
These personnel could also be supplied to the local subsector's Colonial Forces either voluntarily or by requirement.
Also, there's also the Imperial Charter that each member world is granted.
There just might be a clause in there wrt supplying a certain number of recruits to the Imp Regulars w/o specifying exactly how that was to be done.
So, perhaps there are methane breathing units w/i the local, subsector, or imperial units stationed in Yebab's subsector/sector.
