OK, this revamped mission is now BUGGED:
-The grenade clump NO LONGER APPEARS in the southern area west of the tree cluster; either it's no longer there or it's invisible.
-On some of my continued many fails on this mission, a couple troops show up west of where the grenade clump used to be, and the two enemies seem "stuck together, facing each other" and can't move.
I'm not having any luck on this still. Imho it counts too much on rifle accuracy and most of the time I can't hit anything. Sometimes I'll hit 2 enemies in a row and then I'll miss 20 times consecutively no matter where I place the crosshair.
The mortar firing every 2 seconds and never missing on the 2nd "triangulated" shot still strikes me as deeply uinfair.
THEN the one time I could nail the mortar guy with the rifle, another troop stepped up and took over the mortar (!). Give the player a break I say. If you can actually eliminate the mortar for crying out loud give us that much. :p
