There's nothing wrong with the classic white gloves/boots version but I prefer a more modern look.

The head and torso are from the MU Punisher (the one that uses the Jim Lee Cyclops body)
Upper arms are from the wv1 Retaliation Snake Eyes
Lower arms are from a Terminator Salvation Marcus
Hands are from an XMO movie Logan
The legs are from a Dollar General Shipwreck
The guns and gasmask are from Marauders (and boy they do some awesome work)
The straps and gear are various Joe parts I had laying around
