The title says it all, I think it would be nice if the developers added a Sam Browne Belt to finish your military look.
Luckily for you, everyone who wants to be is a developer for CDDA, and a clothing item should be a relatively easy addition for a new contributor. There’s even a nice little guide on how to contribute, all you need is the willingness to learn a bit of github (its far less scary than it looks, trust me) and to actually make the item.
I used to make some ODST armor in versions back for myself, and it never took more than 20 minutes to whip something up from scratch.
