"Land Immediately" or Off-Field landings due to weather are an absolute last-ditch fix for the basic problem which seems to be poor decision making, poor airmanship or non-existant captaincy. Practice at landing in a field would almost be a waste of effort, any helicopter pilot can do that, it is the lead-up to that point where I believe we need to focus.
Not being there is the first place is what I would like to see pilots aim for. If a pilot has to land in a field because he was "pressing-on" then he has missed several stages of correction and is in need of re-education.
