Born in Illinois on 8 September 1980. Jim was lieutenant in the US Marine Corps before he joined IronFall, right at the start of the resistance movement. He is a veteran with extensive experience in the field, but he is starting to lose hope of ever winning the war.

He is one of the few to possess a fully functional set of EX16 exoskeleton armour, a legacy from his days in the marines.

Born in New York City on 22 March 1986. Before the invasion, Sam was an NYPD detective. She met Jim years before, and after a brief dalliance, they stayed friends. It was Jim who asked her to join IronFall. Dynamic and forward-looking, Sam still believes in victory for Earth. She would love to get her hands on EX16 and be at the heart of the fight.

Born in California on 12 January 1991, Victor came from a poor background and joined the armed forces as soon as he was old enough. He befriended Jim in the Marines and followed him into IronFall after the alien invasion.

He is currently convalescing after an injury in the field several weeks ago, which also damaged his EX16. Though he lost nearly everyone he knew and loved when California was ravaged during the invasion, he is young and passionate, and has never doubted that humanity will eventually prevail.
