Something that was mentioned when we were doing heli action yesterday is that we would need a proper area with mostly soft targets that helis stand a chance against. Some kind of insurgent compound with no SAMs, MANPADS, vehicles with ATGMs or 23 mil AA guns (not sure if there's a difference in accuracy of manually aimed and radar assisted AA guns in DCS), but with trucks, cars, the odd IFV, APC or tank, some buildings and insurgent infantry.
Since I know Tom is often busy, I can easily fix something like that up in the mission editor if I'm sent the mission file (I assume/hope it's not huge). I'd just place the units somewhere reasonable from the FARP and not touch anything else.
