Hello! 
But I didn't find excuses I just mentioned that it is quite strange for me to hear that I need to improve my English (but I write historical articles mainly not technical). As I am not a native speaker in English I should improve it for sure, of course. Your example illustrates not the grammar mistakes or errors (this almost never happened) but use of the words which should be fully adequate to context. With this I can agree indeed because I translate texts from Russian into English sometimes directly. In Russian article the original phrase was "strengthened turret armour" [means that it was more thick than hull armour and turret side armour]. 

I need one advice - I would like to replace "Ob'yekt" with more understandable for readers "Object" everywhere. What do you think about this?
Regards,
