Ammo for unsc weapons during campaign ?

are you able to use the UNSC weapons a fair amount in the campaign? is there enough ammo for them? seems like all the videos show the human ammo runs out after 5 mins than its all promethean weapons. Is it better or worse than halo 4 for ammo pick ups for human weapons?

You’ll have to ration the ammo more than any other Halo game.

I don’t think it matters that much, in Halo 2 you ended up using covenant weapons most of the time.

Aw, that’s gonna suck.
