Robert James Sullivan a.k.a. "Scully" is a mercenary hireable from A.I.M., and arguably a distinguishable staple of the series. He appears in all the games from the series.
"Robert James Sullivan is a distinguished member of A.I.M. and is known in the business as a fearless "finisher". When the chips are down and the enemy's jugular is exposed, there's no better man with a knife in his hand than "Scully"."
"The amiable Scully Sullivan is a long-time A.I.M. member. He's one of our most distinguished mercenaries and perhaps the most respected among his peers. Scully holds the A.I.M. record for the highest number of combat engagements in almost as many different countries. Need someone to snap the last breath from an enemy? Then Sullivan's your man. Scully is well-known for his skills with a bladed weapon."
Additional info
Scully is a super friendly guy. He's been married eight times and has twenty one kids.
Though British, he has an out-going demeanor easily mistaken for Australian. His cockney accent, tanned complexion and propensity to call people "mate" doesn't help.
Deadly, yet exhibits no fascination for gore.
We are told, over and over, that Scully is well known for his skill with blades.
He likely holds the record for combat engagements in Jagged Alliance 2 now due to the departure of his old friend Mike.

Notes
Consistently expensive in every game he's in (unlike mercs like Spike, Pops or Len whose prices diminished between games), Scully can generally be considered an "upper tier" merc. He is generally worth his price tag, however, with a broad range of honed skills that make him reliable.
