There is a task about fortifications (i.e. rally points, sandbags, ammo boxes) that are actually used by your team. You cannot just build sandbags in the middle of nothing.
I mean there USED to be one task where simply building things was enough. You could very quickly recognize ppl who had the task in match as they aimlessly built random things bundled together. I was doing that too.
