First guy is wearing Oakley boots, which are actually no longer authorized (pretty stupid that the Army changes its mind since the slide presentation that HAD to be seen about the ACU's included a full slide showing these boots as alright...but then...that's the Army).
As for glasses, odds are they are Wiley X. I say this because it's what's most available in Clothing Sales and too, they're standard issue going to the desert. However, many buy (or already have) their own glasses.
Rudy Project USA is another VERY popular brand. These in particular are my preferred brand as they support the shooting sports a hell of a lot more than Oakley and are very comfortable and are affordable, without ANY sacrifice in quality.
