kaldur'ahm will be focused on rescue ops. possible hooks:
he's an excellent leader (even tho he doesn't always realise it), so if any characters need a team lead or need to be wrangled into teamwork he could be good for it
he will be very keen to help rescue people
he will argue for the stun setting
he's an excellent fighter and will engage una soldiers to allow others to rescue people
he's particularly prone to heat exhaustion and dehydration, so may need a rescue at some point
in a similar vein, he's prone to being self-sacrificial
possibly interested in him dying to save some one else...
