The math isn't particularly reassuring. Arrowhead needs to stop goofing around with these operation completion objectives, whenever me and my friends play helldivers, we do like, an operation per night, maybe two at a stretch. And that's one operation completion, not four. So the active playerbase of, what, a bit over 60-70k depending on how you interpret steam charts and console players (I've seen around 80k from tracker sites but idk how accurate they are for totals that are active) has to complete 500k operations. If every single player was doing it, not failing any missions to break the three mission operation (a rare occurence in my experience but still), all individually, each person would need to complete about eight to ten operations each. Except most people play 4 player co op, so it's more like 50 operations, or 150 missions, over the course of four days. Unless they play on easy mode where operations are a single mission but I don't know why the hell anybody sapient would play lower than difficulty 5.
It's pretty foregone.
