Human made, modern howitzers. Right there for all to see.

True, I wasn't thinking about PvP maps. And I guess that once the traveler came, we could have just started scrapping and re-purposing all of that kind of weaponry

Perhaps this might be nitpicking, but you can see those guns outside of PvP. They're mounted on the Tower proper, underneath that giant window in the Vanguards war room.

I mean if you want to be really nitpicky those guns are all post-collapse and we started out talking pre-collapse, but that's awfully pedantic so let's just not go there ;p
