Licence requirements are based on the laws WHERE YOU ARE. They vary greatly from one country to another, and one US State to another. And YOU did not tell us where your are. In most of the US, no, a license is not required to purchase a semi-auto AR15. Your spelling of 'licence" may indicate you are not in the US. In Australia, a licence is required to obtain ANY firearm. An AR15 is a Class D firearm, and cannot be owned by the average private citizen.
The US Army presently uses the M4 carbine, a shorter and much modified version of the Armalite AR15.
