The troop I was in was like that as well, minus the uniforms. Almost always had to have on either a uniform or troop shirt at outings so we could be identified in case something went wrong. Closest we had to church related stuff was how our troop was grateful enough to be able to hold meetings in a nearby church, a quick mention of it in Eagle Scout court of honor ceremony, and the occasional camp out “there’s service happening for anybody who wants to attend” type of thing.

As for funding, we definitely had the usual fall popcorn sales and then we usually did a bake sale early Spring for funding. Hated the bake sale because it was always at a small rest stop shop that was almost always cold. No external support outside of whoever popcorn sales were done through.
