Darius and company had to move into position, then fire... so the regular guys only get a single shot each, and Darius cannot even fire yet as he needs to brace.  He can move into position to fire and brace in a single round, and fire full auto next round, so if his group surprised the mutants, AND he beats their initiative he'll fire before they do.  Otherwise, the mutants will get to shoot.<br/><br/>That is, of course, if they survive Baromir's 3 elite guardsmen and Baromir himself all firing on full auto... as THEY got into position earlier, told Darius where the mutants were, and have simply been waiting for Darius to move into position before attacking... so they all get to take full attack actions.<br/><br/>So, IF the mutants heard or spotted or heard Darius and his squad moving up before they opened fire (which is not 100%, as thanks to their good tactics rolls, Darius and company knew right where they were going and where they'd be looking to fire at and the mutants wouldn't) then they'll get to roll initiative and possibly fire back at Darius and company before the whole bunch of them open up in full auto... but not before Baromir's squad gets to shoot... which should be quite painful for the mutants.<br/><br/>Cortez, not having the proper skill to be in perfect step with the assault, would still be in position to see the mutants, (having managed to sneak close enough) and open fire at them, although they may have to roll initiative to see if they beat the mutants to it.  (he'll be shooting at them from the side, and will completely surprise them no matter what he rolls on initiative... he just may not quite shoot them before they get to shoot at Darius, if they roll well on their Awareness checks to notice Darius and company moving up, and their initiative checks to beat Cortez's initiative.)<br/><br/>At least, that's what my growing knowledge of the rules tells me.
