Sniper Battle! Kept You Quiet, huh? MGSV OSP Challenge Mission 11

It's time for the Boss to make his way back into the scene! It's time to show everyone why he is THE BOSS and is THE BEST!
This challenge will consist of beating the game with the rule of OSP
OSP = On-Site Procurement.
I arrive to the mission with nothing on me, no primary, secondary, or items, or buddies, or support of any kind. Any item I DO have when entering a mission cannot be used since the game forces a primary and secondary on you before starting the mission. As long as I do not shoot or hold anyone up with that weapon, the rule isn't broken.
Any items I do find are applicable and use to the best of my judgment, however; if I use up all the items bullets or resources, I am out until I can find a resupply within the map or replace with something else.
All the rules are stated at the beginning of the video. When a mission is completed, I am to vacate the hot zone, no chopper extraction unless it is MANDATORY! This is the ULTIMATE OSP Challenge before MGS Delta comes out. Will all the missions be possible bare bones, or will there be some missions where I need weaponry to succeed. Watch and find out with me in this series.
