I've managed a minor victory with 7 KIA and ~16 WIA.
-My main stratagy was security through firepower, basing my attacks off of recon. The disnounted infantry are key, use them to take key buildings and provide overwatch and a little recon. The airbase HQ is a good spot for example, use them to find some of the AT teams and take them with mortar fire.
-Key thing to take the HQ in the first place is heavy supression. Get a lot of Mk19 and M2 strykers up there and ID and hit any RPGs fast, recon by fire often helps.
-When you advance up to the barracks keep your force organized and sweep methodically, avoid exposure when you can. MGS overwatch is useful.
-I've found bypassing the first 2 barracks buildings works well. Take the back row and move towards the harder parts.
-The SF HQ isn't too bad if you can get the upper hand fast, make sure when you hit, you hit hard. Secure your flanks first then move in. Try to coordinate your attack with as much arty and air support as you can, don't lift fire, instead time it so your kicking in the door right when the motars have stopped.
