One of the best iterations of the SOCOM series is easily SOCOM U.S. Navy Seals Fireteam Bravo 2 for the PSP.
Of course, not everyone thinks this is the greatest thing since SOCOM 2.
The presentation of the mission objectives play out like a military game (Ghost Recon or Socom) but with a fantasy twist.
Fireteam Bravo 2 is new edition to the hugely popular SOCOM series.
You can get the headset style (likes the one for Socom) or you can get a handheld one.
