Well here is the issue i have had with it. There was quite a few times i was unable to get a lock on a Tank that was in full view with no trees or bushes around while playing multiplayer, But from time to time i can still get a lock on a BMP that is some what behind trees and bushes. There have also been times when a BMP and a T72 or T90 are in the same field of view with the Jav and i was unable to lock onto the T72 or T90. So inreality i have had issue locking onto tanks in full view, but at the same time i can "accidently" lock on tanks behind cover. There have been plenty of other times also when in hard mode with a clear line of sight on a tank and then launching the Jav and finding there the missle never even hits the tank or even contacts the ground. So in short. i find that if you play on hard difficalty, and the using the Jav, you have a 50/50 chance of hitting the target. With the three suprize choises, Aim fire and hit the target you aim at. Aim fire and accidently hit a target you didnt intend to aim at. Or Aim, Fire and watch the missle go wildly high into space never to be seen again.
