Going to the stashes just to show what's there, no reason to do this unless you need weapons. 17:00 - 17:10 - DO NOT DO THIS unless you want to make things more challenging. Keep the rifle and the disguise, they gonna make the next two missions 10 times easier. If I'm not mistaken, that uniform lets you in even to Ochoa's drug lab, so you all you do - snipe him from the starting point, the rest is just walking.
