EMPERiUM1453 dont said my name but when he said "he was cheating 100% you cant lock on SUV with SMAW when the enemy is not in sight, I was behind the mountain when he destroyed me, never said that about anybody but he IS cheating." i'm sure he was talking about me.
Here a probe from today.
You CAN'T lock with RPG when the enemies are covered by a mountain, wall, house, etc.
You CAN lock them with SMAW.
And if there are covered you can quick shoot to sky and get luck.
