The sound of the explosion brought his head up. Not in an alarmed manner, more of a 'yep, there it is' sort of reaction. Not showing any particular haste, he'd get to his feet and set off at a jog towards the area. He was taking point, if only because his huge and armored body made damn good cover for the two smaller men. Probably safe to assume anyone still outside was getting several bullets in them fairly quickly. For the moment he was working with one of the M16s, but the AA-12 was slung across his back.
At the hole itself he'd pause, three canisters sailing in as he just waited for a moment for the teargas to take effect. "Masks." Spoken to his team through the throat mikes, as he swapped the face mask he normally wore for a gas mask. Then it was into the mess inside. Orders had been simple. Kill anything in an MLF uniform, or anything else killing the civilians. If nothing else, the tear gas would clear out the civilians damn fast and hopefully make them not stop and ask questions about the military-looking folks in bodyarmor sweeping in.
