Why to buy ATGM AFVs?

[EnemyAce]

Ok, there's a good point but tell me how do you play with them? Because moving AFVs into hot area or visible puts them on real danger because of hostile MBTs anf ATGM infantry. With poor armor they rarely survive. If you buy both of infantry and AFV ATGMs roster gets too much toward AT weapons. And now I'm refering to basic meeting engagement of course.
