Translation is not an easy field, and knowing a language is not enough if you are not also knowledgeable in the field. Otherwise, you get gems like this:
"It is necessary to know the characteristics of the following tanks: Russian tanks: T-60, T-70, KV-1. American tanks: 31-T General Chirmen."
It took me a few seconds to figure out what this was supposed to be, but thankfully the original wasn't too far away.
At least it's better than "35 ton tanks" we saw in a previous article.
