All your common issue small arms as they were issued and introduced.
USMC had:
The Canal - M1903 Rifle, BAR, M1928 TSMG, M1917 HMG, and .45 automatic pistol.
Late 1943 to 1945 - M1 Rifle, M1903A1 (Scout-Sniper) w/ scope, M1897/M12 Shot gun, M1928 TSMG/M1A1 TSMG, M1 Carbine, .45 automatic pistol, BAR, M1919A4 LMG, HMG M1917.
USMC Raiders and Paramarines 42 to 44 - M50/M55 Reising*, M1941 Johnson Rifle, M1941 Johnson LMG.
*Some line units did have Reisings as the Reising on The Canal, as they were to replace the TSMG as it was cheaper, yet after the bad feedback and negative field reports from Guadalcanal the Reisings died a quick death and were no longer issued. The M1941 Johnson rifle was bidding up against the M1 rifle, in hopes that the Navy and Marine Corps would buy them and adopt them as their standard service rifle - yet the M1 (Garand) got the order and became as you know THE standard service rifle for the Corps. By late '44 Johnson rifles and LMGs had been phased out.
US Army had:
The Canal - M1 Rifle, M1 Carbine, BAR, M1928 TSMG, M1917 HMG, and .45 automatic pistol (service revolvers as well - but far less common as the .45 auto).
Late 1943 to 1945 - M1 Rifle, M12 Shot gun, M1903A1 (Sniper) w/ scope, M1A1 TSMG, M1 Carbine, .45 automatic pistol, BAR, M1919A4 LMG.
