Nor would I advise anyone in a hummer with a mounted crew served weapon (50 Cal, MK-19) to dismount. the firepower is too valuable
It's everyone else with small arms. Vehicle mounted systems can suppress, but unless the terrain is favorable (and if the bad guys are smart they'll set up an ambush where it isn't) they don't have much of a chance of chasing down foot mobile attackers in a semi urban area
Go after them, every minute you stay in contact increases your chance of getting them.
This ins't Vietnam or the JRTC. There's no company level baited ambush waiting for you. Just at most a couple of dozen assholes running for their lives after taking what they thought was a free shot
All the best
