Hopefully this can help some people
Basically If you've just started your game don't worry to much about the tasks just go for s-rank in all missions because later you get far superior weapons/equipment/outfits etc which make it easier.
For 90% of the tasks use Stealth camouflage , the Raiden outfit and Quiet and you should find this pretty straight forward! I would do a few tasks at a time and not try do them all at once as it just makes it harder. Most guides tell you to use ddog but for me thats rubbish, Quit can scout an area and help you take lots of enemies, she wins every time in my book.
I'll share some things I did or that happened during my play through .
Mission 45 A quiet exist This mission is an absolute c*nt! , it's one of they missions that you will shout all sorts at your tv, soldiers see you when in stealth and even with the little chicken hat they magically still shoot you.
For the
task extract 7 tanks and 7 armored vehicles I equipped the skull outfit, mist, armor , normal stealth camouflage, anti tank stun mine, rocket launcher for the helicopter and an assault rife ( which was pretty useless).
As soon as the mission started I activated the skulls mist and called in the sandstorm weather modification. I told quiet to cease cover fire because she killed a few vehicles and I had to restart the checkpoint a few points. I would run at the Tanks/Trucks with stealth extract them then quickly run back towards the palace to regroup. I would switch quickly between stealth,skull armor and NVG because you can't see a thing from the sandstorm but you need the cover . Place an anti tank mine the one that stuns on your left hand side as a tank comes from there eventually. I also placed about 4 on the rind hand side in a straight line next to the generator because a few tanks drive to the place in that line. Apart from that you need a lot of luck.
Mission 33 Subsistence C2WAfter you deploy head right up to the Eastern Communications Post, There is a crack on the wall which leads to a secret path which takes you to the diamonds. Once you have the diamonds keep going around the path and you will arrive on top of the enemy base. Stay on top of the mountain and call in your helicopter for pick up right in front of you ! . Usually the chopper would disappear under enemy fire but in this case the chopper will take out all the guards ! leaving you to extract the container and destroy the transmitter with ease! one thing that happened to me was
make sure you identify the transmitter before destroying it or it might not count ! this happened to me. Just look at it through the binoculars. I originally got the prisoners first,if your really struggling just wait until the sandstorm its always early morning in game, although theres only two guards watching the prisoners so after a few tries you should get them unnoticed. The two prisoners are at the left hand side of the base in the first buildings you come to , just watch out for the claymores. The first prisoner is easy its the second who is harder to get.
Hope this helped some people, Any questions message me and I'll try help. cheers
