I wanted to add that, to my mind, one of the most prominent side quest lines that includes Dragoons (in drachenmail and everything) isn't about killing dragons...
It's about scouting a newly discovered land (that admittedly has a lot of dragons in it), and making first contact with a new tribe of peaceful beastmen (the Moogles). Dragoons place aetheric readers, make maps, and make reports on the nature of the creatures they encounter in so doing.
(headcanon incoming)
If they aren't dismissed from the army entirely, then that's what I'd wager they are doing post-War. Being at peace with Hraesvelgr's brood and Nidhogg's brood being scattered means there's a lot of Dravania and Abalathia's Spine that's now safer to explore - and hey, now they're not constantly engaged with Nidhogg's brood in skirmishes on the city's wall, they probably have resources to spare to do that. I doubt they'd send Dragoons on strictly diplomatic missions (they aren't exactly trained for social skills) but they might retain their secondary role as scouts and pioneers, even now they've lost their primary role as dragon-killers.
They probably have new job titles, and may or may not retain their drachenmail (maybe as a sign for other Ishgardians to respect them? Perhaps if they're sent somewhere there might be remnants of Nidhogg's brood? Can they Jump - a useful skill for rock-climbing or gaining a vantage point - without it?). But they were already trained to do this. Surviving in new, likely hostile lands, learning about them to the extent they can start to use the terrain to their advantage - it's all part of fighting dragons that can carry you away on a whim. But it has peace-time uses, too.
And there's always the remnants of Nidhogg's brood, too. The last thing you want is to dismiss all your dragon-killers only for one of Nidhogg's seconds to rally a last-ditch attack. Maybe this is why "10 Dragoons" - a skeleton crew that wasn't reassigned, just to handle any enemy resurgences? I'm sure if more dragons started causing trouble than a handful, they'd start calling back people who were already trained ahead of training new people, but they have a country to rebuild - they probably don't want too many hanging around.
