Yeah, still lotsa ways to deal with the armour-bound tankork truck there.
Gas, mana spells, tight quarters close-fighting (see what kind of conditional penalties might be applied if he's stuck fighting in a vent), drowning - probably a few dice penalties for swimming with all that paddin'. Sonics - the elemental effect in Street Magic ignores that protective goodness...
And if all else fails? Non-combat encounters that are necessary for the run's success, involving the tank. Suddenly they need to talk their way out of an awkward situation - media coverage, somebody's loved ones found hostage, a dragon...sure, that one dude might survive if the lead starts flying, but if he starts it, and his friends all die or are horribly maimed, he's not gonna be very well-liked after that, is he?
Or a meet that requires everybody showing up unarmoured, and unarmed. Sneak in stuff? Sure, but no way are 20 points of layers getting unnoticed. Could be live, or could be a Matrix situation.
Enjoy the possibilities.
