Here's how Russians plagiarized the original American weapon Stinger from the computer game

Lately Ukrainian bloggers found a fake shoulder-carried missile launcher "Stinger" in videos, which were filmed by pro-Russian separatists from the Luhansk People's Republic in the Eastern part of Ukraine.

Journalist and blogger Anton Logvinov, wrote about the computer game industry, observed that in the man-portable air-defense system (MANPADS) video was made on the basis of the model of "Stinger" from the famous computer game Battlefield 3. The similarity сonsists of the spelling mistake in the inscription described by MANPADS - TRACKING RAINER instead TRACKING TRAINER. This mistake has occurred in the video and also by game designers of the Battlefield.

The video contains other pitfalls  for instance the inscription on the box and RE USABLE DATE LOUDED. In addition, we can also observe some traces of alterations to it.

On the detection of an alleged warehouse of American weapons for "Stinger" many publications wrote about, including "Komsomolskaya Pravda", the TV channel "Star", and RIA Novosti.

Here also i give a translation of some moments from that link with some photo proves:

So we can specify indiscrepancies as seen in this
video. Signwriting on the boxes
RE USABLE.

What's wrong with this? It was a simple error made in the labelling. On the real boxes REUSABLE, or RE-USABLE is written. What does "RE USABLE" mean?The answer can only be given by experts from the Luhansk or Donetsk People's Republics. Illiteracy, multiplied by the stupidity and inability to rewrite some simple English words.

The second inscription on the box. US APMY. What the hell? Perhaps, UP ME? Oh no, ARMY. Frankly speaking, what's the difference between a Latin or Cyrillic? Р and R?

The third inscription in the box  DATE LOUDED.

Why louded?  Is it difficult to understand for a man, when he wrote a set of letters. LOUDED, or LOADED - there is a difference, louded is not a word. And indeed there is no date for when this was "louded". Apparently, they were too lazy to look for good photos in Google.
Here is a real image with the appropriate labelling with the date of loading (and on the side, RE-USABLE, but not RE USABLE):

The label on the sideTRACKING RAINER. What? What does that does that mean?

Of course, in the original it should be
TRACKING TRAINER. Which means no more than a training module. But the cheaters and fakers of MANPADS found in Google images the photos of the Sting and copied the labels, but failed to so correctly.

a) a poorly executed weld.
b) characteristics (holes) in the Stinger MANPADS are not present.
