A bazooka or other such shoulder fired anti-armour weapons are technically small arms as well (small arms being anything that can be fired by an individual holding it in their hands or mounted against or on the shoulder), though more specifically they would fall under the light weapons part of the SALW category (Small Arms and Light Weapons) which includes things like heavy machine guns and grenade launchers"Small arm" = AK
What is normal arms? Bazooka?
