AIT rifle shooting / training

Do we have people here that are or had been involved with US Army and/or US Marine training units and/or range masters, etc. that have familiarity regarding how many rounds with the rifle were normally fired during training of:

Advanced Infantry Training of the US Army?

US Marine Training beyond Basic Training?

Would all of the services have been comparable for rifle training through basic?


Has there been any significant change with this over the years? Thanks
