Yes, but that is a skill based avoidance of DPS, what's the point here?
Forcing squads to position to fire is fine, it requires intense micro from the player trying to pull it off and it is still really hard.
Like avoiding the timers on sniper cloaking? That's being considered a bug to be fixed.
And while what I described is probably the least effective method possible, the plethora of sight and shot blocking mechanisms in this game that are constantly present on the battlefield is worthy to note.
I think it is as much of a challenge move CQC units to point blank than it is to keep any kind of infantry at something other than point blank range.
