But remember that Turkey is a NATO ally, so you're up against the NSA, CIA and MI6 for starters (in addition to the fine intelligence service of Turkey).
So I would think that Signal would have to hand out all registered phone numbers in Turkey - a list which could be checked against all military personnel. Given that they've detained thousands of teachers, I don't think they'd be above detaining thousands of suspected troops, even at the risk of waterboarding loyalists.
You don't need an accurate list, just some help "short listing" people.
Similar issue with Tor - if you're in the military and your mobile device used Tor before/during the coup, you'd be on a watch-list (or shot).
The best op-sec is the terrorist/stay-behind/contras: small independent cells, with no knowledge or communication with each other. Obviously some plan is needed to set up a command and control structure when the coup is "won". I don't think there are any great solutions here, that also doesn't leak enough meta-data to get you tortured and killed in the event of a failed coup.
