The idea is generally sound its just to accurate, use it as I think it was intended. It shows you the area that fire came from just in case you had the zoom level wrong to see it. So just remember near those trees rather than straining to remember the hex.
ATGMs are the one unit I tend to micro manage & prefer to buy separately from the company rather than imbedded.
Low ammo count & sometimes they are your most powerful penetration wise armour killer.
I buy them last so only fire if everybody else failed & set the opfilter so they don't engage soft vehicles & light armour. This saves a lot of management issues as they only tend to fire when they need to.
