Software Friction

As a Dutch ex-Navy officer, we just called this "friction" as everyone had read Von Clausewitz during officer training and was familiar with the nuances of the term. Militaries overwhelmingly address this problem by increasing redundancy, so that there are as few single points of failures as possible. It is very rare to encounter a role that can only be filled by a single person, a well designed military organization will always have a plan for replacing any single individual should they accidentally die.

"I can make a brigadier general in five minutes, but it is not easy to replace a hundred and ten horses" -- attr. Lincoln (exact words vary by source)

It's noticeable how few computer wargames simulate any of this, instead allowing for frictionless high speed micromanagement.

In military Command and Staff Training (e.g. for training large HQs), the solution to this is that the trainees don't use the simulations themselves. Instead they issue commands using emulated C2 systems to role players ('lower controllers') pretending to be subordinate forces, who then execute the orders using the sim, and then report back what has happened, as far as they can tell. This generates quite a lot of useful friction. Another group of role players ('higher controllers') represent the HQ superior to the trainees HQ and in turn issue them with orders. The role players and opposing force are also following direction from exercise control (EXCON) and can easily be used to dial up the pressure on the trainees. There is a small industry (e.g. [0]) supporting the exercise management systems that keep track of the various 'injects' that are fed to the trainees via the role players, or by simulated ISR assets, etc.
