In this summers multi-enemy clinic one thing I stressed with my groups is always be trying to get all the enemies in the same hemosphere in relation to you (ie. you can find them all in the same general direction). Once you do that, it makes the SA job a lot easier.
Here is a short film example that happened last night.
multi.ahf I can't stress enough how much SA goes hand in hand with this. I could probably fill a page with just the SA observatoins/though processes going on in the first minute. Just as an example though, in the first seconds of the film, I am actually looking off to my 2 o'clock trying to judge the timing on when the FW 3500 yards away will come within firing range, so that I have an idea when and where to maneuver to not provide a good target (on the blind).
Yes, the synopsis is I got into a 5 on 1 (not counting the typh) and worked it so I could bug out. Once I got them all in the same hemosphere...cya! Any 3v1 or greater, co-E or worse, that you can walk away from is a win in my book. Total film was 48 mins with 9 kills landed for the sortie.
