RPG 42 is able to lock and hit vechicles at much longer disstances when NLAW. More then 1 km for RPG versus nearly 700 meters for NLAW, and RPG have nu such a bug.
I had tried to reproduce this issue on DEV build and the issue are here as well. More than this in DEV build i failed to get rockets from the crate with my RMB (but this have no relation with current issue).
