A fully automatic weapon means you can hold down the trigger and it will continuously fire. Semiautomatic means you fire one round for each pull of the trigger. A selective fire weapon is capable of fully automatic fire, and lets you select between the two. To own a fully automatic weapon in the US, you need a Class III National Firearms Act tax stamp for the firearm. The importation of fully automatic weapons for civilian sales was barred in 1968, and the domestic manufacture of fully automatic weapons for civilian sales was barred in 1986 - however, weapons of either type manufactured before the effective date of their import/manufacture can still legal be transferred between licenced civilian owners.
The M1A1 nomenclature was applied to a variation of the Thompson submachinegun, which was an automatic weapons. As far as the .30 carbine goes, M1 designation was applied to semi automatic variants, whereas the fully automatic versions were known as M2.

In order to purchase a fully automatic weapon in the US, it must have been manufactured and NFA registered prior to the passage of the Firearm Owners Protection Act of 1986. Any fully automatic weapons manufactured after that date may only be transported to you if you are an FFL dealer with the appropriate Special Occupational Tax stamp, and a law enforcement letterhead authorising the transfer to you. However, most "automatic" handguns are actually semi-automatic, not fully automatic. Those are legal, and in the US, regulated as ordinary firearms.
Because its fully automatic, and was not importable pre 1986 (when the assault weapons ban was introduced). Only fully automatic weapons produced pre 1986 and were already legally owned in the US are now legal in the US. Although it IS legal for Police Departments to own Glock 18's, if they have been trained by Glock. It is also legal to own (in certain states, with strict stipulations), a Glock 17 (or any other model besides the 18) with a fully automatic sear. Which is essentially a Glock 18. **I Am NOT A Lawyer***
You can. It is not against the law to own fully automatic weapons provided you follow all the rules. 21, clean criminal record, money to buy, CLEO signature, etc..
No, the ban on automatic weapons was never lifted. Fully automatic firearms imported before the passage of the Gun Control Act of 1968 and manufactured domestically before the passage of the Firearm Owners Protection Act of 1986 (including imported firearms refitted with the appropriate number of US made components required to be considered US manufactured firearms) are still the only fully automatic firearms transferrable to civilian customers. Licenced FFL dealers with the appropriate Special Occupational Tax stamp may still receive imported and domestically manufactured automatic weapons after those dates, but only as dealer samples, and these cannot be transferred to civilian customers.
The Vietnam War was the first helicopter war & the first war in history in which every uniformed combatant on both sides were armed with fully automatic assault rifles (M16s/AK47s).
