Sorry, Rhino, that is not true.
Here are some terms:
Full power rifle cartridge: .308, 30-06, 7.62x54R, 45-70, and others
Intermediate power rifle cartridge: 7.62x39, 5.56x45, and the Russian one designed to compete with it.
Pistol cartridge: I hope I don't have to define that one for people here.
Machine gun: Shoots a full power rifle cartridge via a belt. Fully automatic, may have other modes. M2, M60, etc.
Sub-machine gun: Shoots a pistol cartridge in select fire, single shot, full auto, sometimes burst. HK MP5, Thompson, the Greasgun, Uzi, etc.
Assault rifle: Shoots an intermediate cartridge in select fire, single shot, sometimes
full auto, sometimes burst. The STG44 German Sturmgewehr "storm or ASSAULT rifle" was the first, and it was literally name Assault Rifle. The M16 and AK47 and variants are assault rifles.
Battle rifle, sometimes Main Battle Rifle. Shoots a full power cartridge in some form of fire. I say some form because main battle rifles were bolt action in the first world war, when all they had were springfields, and semi-auto in the second. However, it is usually meant to be at least semi-auto. The M1 Garand is the original in most regards. The M14, FAL, G3, are typical battle rifles.
Assault rifles have shorter barrels, and shoot smaller cartridges than battle rifles. SMGs have still shorter barrels and shoot pistol rounds.
So, to split tacks, in my opinion, the AR10 is a battle rifle, the AR15 is an assault rifle, albeit both are semi-auto versions of the Real McCoys.
