Does anybody else fight off the CSAT reinforcement on the campaign's Supply Network after you hid the truck?
I did it for the second time on my second playthrough and it's pretty fun, destroying the helicopters with anti air missiles and the Ifrits with the HE rockets provided at the back of the hut. Then I snipe off the specops guys running around the hills. I always find it worthy to fight them off and escape afterwards, because they drop good loot such as Kalibas with suppressors, marksman rifles with scopes and assassin csat armor. I also use a simple mod to be enable to wear enemy uniforms so a bonus for CSAT armor.
