For what it's worth, Iceman does serve as a field leader/second-in-command to Cyke in one of my fanfic series, which means the mutants under his "command" are:
Northstar
Warpath
Jubilee (re-powered)
Blink (from Exiles)
He is, as some have discussed, not very good at it yet, as typified by this exchange:
Iceman: "That was me leading."
Warpath: "Well, stop it. It's annoying as ****."
Iceman: "I know. I learned from Scott. He's the best at that."
*shrug* That's basically my take on the subject...
