Where do you get the ak 47 in Metal Gear Solid 2 sons of liberty

The AK-47 does not appear in Metal Gear Solid 2: Sons of Liberty. However, at one point in the Plant chapter you are required to obtain an AKS-74u to impersonate a Gurlukovich mercenary. You must return to the Struf F warehouse and enter the Lvl 2 room in the lower level to the north. There you will find the AKS-74u as well as a suppressor attachment.
