Just like in the movies

And we all know that if those bad guys were smart they would all just attack him at the same time and take him down with ease. But no! They insist on attacking him one by one while the rest just watch their allies get knocked out. We all know how stupid the bad guys are and we all like to laugh at those moments in the movies.
So my question is. Why does people to excatly the same thing in WoT??
"Oh look, it's just two enemy tanks hiding behind a house and we are 5. Lets send in one tank at a time to try and take them out!"
