Poorly explained diagram from article. I think "BTG" is some kind of battalion sized unit. What is the difference between a "BTG" and a battalion?

Here’s some links which may help with the explanation ; short answer is :

A BTG is a motorized rifle or tank battalion of 2-4 companies with attached ATGM, artillery, reconnaissance, engineer, and rear support platoons making a fairly self-sufficient ground combat unit.
