Marine platoon org 1942. I do believe they still had Springfields. If I am counting correctly they have five BARs in a platoon.
The D-1 Squad and platoon is of interest because of its 9 men number, and the platoon was assigned an "Automatic Rifle Squad".

Fig 1. A Marine Rifle Squad in a D-1 organization.
The Platoon consisted of a Headquarters Element with:
1x Platoon Commander (A 1st or 2nd Lt)
1x Platoon Sergeant (Platoon Sergeant)
1x Guide (Sergeant)
1x Demolition Corporal (Corporal)
3x Messengers (Pfc/Pvt)
It had three Rifle Squads each with:
1x Squad Leader (Sergeant)
1x Assistant Squad Leader (Corporal)
1x Automatic Rifleman (Pfc/Pvt)
1x Assistant Automatic Rifleman (Pfc/Pvt)
1x Rifle Grenadier (Pfc/Pvt)
2x Riflemen (Pfc/Pvt)
2x Scouts (Pfc/Pvt)
There was also an Automatic Rifle Squad with:
1x Squad Leader (Sergeant carrying an SMG)
2x Automatic Riflemen (Pfc/Pvt)
2x Assistant Automatic Rifleman (Pfc/Pvt)
3x Riflemen (Pfc/Pvt)
The BAR count was increased after initial experience in the Pacific (1943 version). I'd imagine something like this with M-4s or M-1 carbines for the non riflemen.
