Solid Snake & Gray Fox vs Master Chief & Arbiter

Who do you think would win in a two-on-two match between Snake and Gray fox vs Master chief and Arbiter.

Weapons
Snake: Socom, Famas, 2 Frags, 2 C4
Gray Fox: HF Blade, Arm Cannon
Master Chief: Assault Rifle (Halo 1), Pistol (Halo 2), 4 Frags
Arbiter: Plasma Sword, Plasma Auto-Rifle, 4 Plasmas

Arena
Heliport from Metal Gear Solid 1 (aka Twin Snakes). MC and A start on the upper section where the second ventalation shaft is and GF and SS start at the elevator. Who will win?

I personally think Gray Fox and Solid Snake will win because Gray Fox is the fastest one there, and both Solid Snake and Gray Fox are experts in stealth. The only good stealth member on Master Chief and Arbiter's team is Arbiter because he has the stealth camoflauge.
