So diffar has only about 1 nm range ? Is it really that weak ? Please tell me how you detect sub in area 20nm x 20nm with that ? Even if you can select loadout it can be a trouble, but let's talk about FFG + helos, since most missions for FFG are exactly like this. And what more, usualy you start on the border of the are or even in the middle of the area, so you really don't have a time to do deploy nice SB field.
Some missions are just badly unbalanced. You are ordered to do impossible things.
Well don't get me wrong .. I enjoy even impossible missions
