Like Generation X, X-Force's involvement with "Operation: Zero Tolerance" was on the periphery. Nothing in the two tie-in issues (technically four though two are unbranded) impact the main story or deal with Bastion. But unlike James Robinson's efforts on Generation X, X-Force writer John Moore seems interested in telling a good story. Moore ties the events of "Operation: Zero Tolerance" into ongoing subplots and character development that makes these issues work effectively as part of the larger story while still feeling distinctly X-Force.
Moore uses "Operation: Zero Tolerance" as a way to forward strong character threads for Dani Moonstar, who makes a return in a big way, and Domino with whom he creates a personal connection to one of the Zero Tolerance troops. And perhaps most importantly, the events featured in the pages of X-Force leave a lasting impact on the series.
