[Brother in Arms]

I am kinda of the Maestro of battle rifles so here is my take on what a "battle rifle" vs. an "assault rifle" and is mostly dependent on caliber and conception of purpose/use on the battle field. These are my own definition between the two, both firearms have been used as standard infantry rifles which is where I believe the confusion comes from hopefully this helps in understanding the slight variantion in both types of firearm.

(ASSUALT RIFLE): a rifle that fires an intermediate cartridge, is capable of select fire and is fed by a detachable magazine.

(INTERMEDIATE CATRIDGE): a catridge that is greater in power than a pistol/SMG but less powerful than a full power rifle catrige.

(SELECT FIRE): Capable of Semi-automatic fire as well as full-automatic or mutilple round burst or both. The SELECT meaning the ability to choose one rate of fire or another.

(BATTLE RIFLE): a rifle that fires a full power rifle catridge, maybe select fire and most likely is fed from a detachable magazine.



Hopefully that didn't cause more confusion I will use examples to distinquish the two types of infantry rifles.
ASSAULT RIFLES: AK-47, AKM, AK-74: in calibers 7.62X39mm and 5.45X39mm as mentioned all fire an intermediate round are select fire (Semi-auto or Full Auto) and are fed with detachble box magazines. M16,M16A1,M16A2 all in caliber 5.45X45mm, select fire Semi-Auto or Full-Auto or Semi-Auto and 3 round Burst and are fed with detachable box magazines.

BATTE RIFLES: M1, M14, FAL, G3A3 in Calibers 7.62X63mm, 7.62X51mm. The M1 is Semi-auto Only, the M14, FAL and G3A3 are Select fire capable Semi-auto and Full Auto. The M1 feeds from an 8 round internal clip. The M14 can be fed with 5 round charger clips or fed with a deatchable box magazine. The FAL and G3A3 are fed by detachable box magazines.

Caliber is the easiest distinction, INTERMEDIATE CARTRIDGES are 7.92x33 Kurz, 7.62x39mm, 5.56X45mm, 5.45X39mmm to name a few.

FULL POWER RIFLE CATRIDGES: 7.62X51mm, 7.62X54R are the the most common with 7.92X57, .303 (7.7X56mmR), .30-06 (7.62X63MM) as older but excellent options.
