I do not see a bug here. The difference is caused by the difference in P.
There is no such a thing like "difference in P"... This is the same scenario with the same batterie, screenshot on the same distance against the same (and only) target.
You shouldn't use UPR with I87V!
In T/T, they should try to fly on the boresight, they should not lead it.
I know. This is against the rule. Now what? Court martialed?
EDIT:I apologise for missleading:
It appears that when we are in the position of 3/250 rd PVO, Karlovcic, Hammer-34 kills you... So, it's not a bug, but a dead end (exept killing Hammer first...
Does killing the carrier kills the LGB mission???
