Bayverse is pretty much a no-brainer. Bay stuff is usually pretty pro-military and apparently the NYPD knows about the Turtles after the second film, so it's not too much of a stretch that it might leak to the military and they get recruited in some way. I can't go that route because I slept through most of the first film and never even tried to watch the second. (The falling asleep is nothing to do with the quality, I also apparently slept through chunks of multiple Star Wars films. An undiagnosed thyroid issue was to blame. I have no idea if the films are any good or not.)

'03 cartoon: I see multiple ways this could play out. 1. Turtles have been transported to the Stargate universe in some way and the only transport and/or alien technology/information they can find is the highly classified Stargate Project (SP). From there it becomes a matter of what mood am I going for here? Is this a comedy, or am I playing it straight? Do I want the Turtles to be good enough at stealth/infiltration to be able to sneak into the base and take control of the gate, or do they get caught before that? Do they think the Tok'ra are this universe's Utroms? 2. The Turtles are just aliens that are discovered on one of the planets a team travels to. Possible twist: actually they were regular Earth turtles (and rat) that the Goa'uld experimented on and turned into people! 3. It's all the same universe and the EPF captures the Turtles and wants to experiment on them, but SP calls dibs. 3a. Turtles are forcibly recruited under threat of being returned to Bishop. 3b. Turtles are benevolently recruited and have the choice to turn down the offer and go home. 4. Same universe, rumors of mutants in NYC reach SP, they go and capture them. No Bishop or EPF involved. 4a. Forcible recruitment under threat of experimentation. 4b. No-strings job offer. 5. AU where Bishop works for SP and convinces them the Turtles are aliens who snuck under the radar (possibly even believes it himself). Captures them, testing reveals they're 100% Earth critters, someone less xenophobic takes over. 5a. Forcible recruitment etc. 5b. No-strings job offer etc.

Rise: 1. Some variation on just about any of the '03 scenarios. 2. Possibly an additional scenario where the Yokai government and the US government are aware of each other and sometimes work together and somehow they get recruited (forcibly or otherwise) through that. 3. IDK, did the military show up in the movie? At the very least, they were probably at least aware of the fucking ALIEN INVASION. Anyway, they find out about the Turtles because of that and SP got copied on any communication about it. 3a. Forcible recruitment etc. 3b. No-strings job offer. 4. Donnie just fucking gets caught hacking them and SP tracks them down from that. 4a. Forcible recruitment etc. 4b. No-strings job offer. 5. Ninpo is just a super fancy version of the Ancient gene! 5a. SP is able to track their usage and...again, forcible vs. voluntary recruitment. 5b. The Hamato family are (somehow) known to have a very strong version and they go recruiting. Forcible vs. voluntary recruitment etc. 5c. Getting mathy, Hamato Yoshi and the Turtles were supposedly mutated in…~2005. Atlantis expedition was started in 2004. If we ignore or claim AU on Yoshi being kidnapped in ~1995, they could've somehow discovered he had the gene and attempted to recruit him at the time. He turned them down, blah blah, somehow this results in either SP tracking him down again or the Turtles getting curious and looking into it. OR the Goa'uld attack Earth and Splinter reaches out to SP and offers to help. 5d. Someone from SP is in NYC and has some sort of Ancient tech on them that reacts to the Turtles and leads to them being discovered. Forcible vs. voluntary recruitment.

MM/TOTTMNT: These boys are just straight up US citizens at this point, I guess? They can join the military if they want once they're old enough, and get recruited the same way anyone else does. (At this point it has been TWENTY YEARS since the Atlantis expedition started. Almost thirty since Stargate Project started. Definitely thirty before they're old enough to join the military. At this point, I might be tempted to update the Stargate timeline.)

Uhhh, that's all I got for now.
