Samawah, Insurgents
Alright, I've been at a lose as to how I'm going to post my tactical post, considering I'm still a CS player by habit, however, A few nights ago I lead a clusterpiff of random regular players in a flawless victory on Samawah, and I figure i'll post how I organized it.
By flawless, I mean that the Insurgents didn't lose a single round. EVER. Straight to the next map.

1. From spawn, we split to two groups. 3 People go to Alpha, with the intent of capping, but really more to simply distract the marines. The rest go to Bravo.
2a. While capping bravo, if 3 or more are already capping, send excess players straight to Delta for a diversionary attack. (3b) Once Bravo is capped, head Straight for Charlie through the side alleyway. Kill any marines hiding around there. (3a)
(4a)The moment Charlie is capped, run straight for the rear of delta. Cap it. leave one or two behind at Charlie to defend it.
After Bravo, Charlie, and Delta are capped, leave a small defense at Charlie and Delta and have everyone else rush Alpha. If Alpha has already been capped, the we won! Woot woot.(5a)
