Well, there are a couple 'gauntlet' type missions, no doubt. But there are plenty of missions and published modules where there are plenty of noncombat options. For instance, I was in a group doing On the Run where we barely touched gunmetal the whole run. Granted, we were more the 'do the job, get paid, go home' type, rather than 'investigate everything about the job, the johnson, and every single person involved' type, so we didn't run into any double-crosses or vampires. The only time in a Mission I read that had something like charging into a bug's nest was one time where you were literally bug hunting, and you had the option to grab some KE IV rounds and grenades first. Granted, I haven't really read the 5E Missions that closely.
