The AK-74 and the SVD both work on the same piston driving operating system as the AK-47 but fire different types of ammo.
Actually, the SVD differs in that it uses a short recoil system, rather than the long recoil method of operation.
AK variants are countless, and are naturally related. Some countries which did not adopt the SVD developed their own designated marksman rifles, which did use the same method of operation as the AK - most prominent of these two would be the Romanian PSL and the Yugoslav M76. The M76 was manufactured in 7.92x57 for the JNA, but export versions were offered in 7.62x51 and the Soviet 7.62x54R (the latter of which was manufactured under licence in Iraq).
Aside from those, the Galil is derivative of the Kalashnikov, as is the Indian INSAS rifle. The Belgian FN-FNC and Mexican FX-05 rifles also use an operating system based at least partially on the Kalashnikov.
Literally, millions. There were made by Russia, China, and many of the Soviet allies. While more AK47s have been made, there are a LOT of SKS rifles out there. No exact number are available.
AK47s and tanks.
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).

With bulletproof vests and AK47s.
Depends. The original military AK47 is capable of fully automatic fire. In the US, Federal law requires it be registered as a machine gun. However, most AK47s sold in the US are semiautomatic. MOST states do not require registation of rifles.
Depends if you buy an aeg or not. Although I don't believe they even manufacture spring AK47s. There is no set AK47 brand. there is at least one thousand different AK47s.

The same as any other machine. Raw materials are purchased and made to specifications.
