OK - Kim and Kareem - if you are up to it - carry your weapons concealed and start a loud verbal argument (play fighting would not hurt either) about a topic of your choice.
Try to draw the guards (as many as possible) to the front entrance on the side that appears to block the LOS of the tower guard as much as possible (so Ghost will not be seen taking out the guard at the tower and keep him from shooting at us). Looking at the map from GC, that would be the lower left entrance.
Once you have done all you guys can to attract the guards, one of you give a major fake sneeze (AAAAHHHHHHHHHH CCHHHOOOOOOOO!!!!!!!!!!!!) and then expect the flashbang. After the clink of the grenade on the floor, dive out of the way and cover your eyes as you draw your weapons. I'll open up on the blinded guards with my assault rifle and close in.
Ghost, if this seems ok with you, try to take out the guard at the tower following the sneeze. Hopefully, we can time your shot and the explosion of the flashbang at the same time.
Everyone OK with the plan?
If so, let's do it (but make sure everyone knows what to do by radio commmunicastions before hand)- I'll follow your leads.
