GATE: Jieitai Kanochi nite, Kaku Tatakaeri

No, they would volunteer for their own sake.

That makes no sense imo. How would they benefit from doing that? The only reason why they'd volunteer is because they don't want to lose a friend/itami and be responsible for it because "they didn't go with him".

As I understood it, he earlier refused the idea of a resource scouting party. You can't really expect anybody to take seriously that this one man is qualified for it unless he has a master's degree in geology as well in addition to everything else. Not that it would make this show any less hilarious.

He was supposed to be on his way to the capital, after being commanded to return there. Yet he decided himself he's not going there. Instead the HQ commander will soon learn Itami took a car, weapons, and food and went who knows where (since only the dark elf knows where). That is not how the military works.

I'm pretty sure glasses guy changed the rules for him and the "ressource operation" was never fully out of the question (glasses guy even said that he'll be waiting), he just made it more troublesome because it was a last minute decision. They know where the dragon is so it's not "who knows where" either.

To conclude, the fire dragon is either a military matter, or it is not. Defeating it for a single girl´s sake is ... too shounen, as Kraco said.

And thats not what is happening. The whole episode was about how both the military and Itami couldn't afford to send poeple to their death officially.
In season 1 they even talked about how the military would've to invest troops and armor to destroy that beast and that its a difficult thing to do, even though they know how much trouble it causes.
It's not like the JSDF doesn't *want* to get rid of it, they even said that they would like to help, but can't because of political reasons.

So once again, that he goes alone is clearly all about him being MC and to keep his reputation going.. (if we'd have a problem with that, we wouldn't watch anime or movies, because MCs are gonna mc-ing the shit out of every show)
That the military doesn't officially make a move here however, is a totally different matter and the reasons have been given much, much earlier in this show.
