going a few steps further than the coin tosses or dice rolls...
I had considered making an excel spread sheet on my laptop with a grid reference as a cell entry such as "BF GRIDS NORTH HALF" and "BF GRIDS SOUTH HALF" and so on and so forth until the given grids are entered into excel for the northern and southern halfs of each grid reference.
if i find myself patrolling a specific area, say AF79 for example... i can go to my laptop in excel and select "AF GRIDS SOUTH HALF" since i am in the southern half of excel....
once that is selected it will correspond to a list of about 5 to 10 "virtual orders" on a second excel page out of those it will select one at random.
for example... if i selected the cell which represents "AF GRIDS SOUTH HALF" one of the randomly generated orders might be "Proceed to grid AN16 and observe task force activity west of Lerwick."
It would be time consuming to create such a file, but in theory you could come up with hundreds or perhaps thousands of possible virtual orders and they would all pertain to your situation ie... no being rerouted to gibralter from norway.
