Do the side ops
As soon as you’re given free rein of the game, check your Side Ops list and do the interpreter mission. This mission requires you to extract an English-speaking Russian soldier from the field and recruit him into Diamond Dogs. It doesn’t sound too important, but this will actually help you out a lot as you’ll now be able to understand what your Russian foes are saying.
Metal Gear Solid V also lets you interrogate your enemies and extract info from them – handy if you’re looking to snag some extra rewards during a mission. There are a couple other interpreter missions other than the Russian one that will become available later on as well. Make these your priority as soon as they pop up, and you’ll have a much easier time dealing with your foreign enemies on the field.
