How to get the cutscene where motherbase staff fights each other in MGSV?

Please make the answer for this question as unspoilery as possible.
I am about two-thirds into the main missions in The Phantom Pain and I've felt a need to get the cutscene from the trailer where:
two Diamond Dog mercenaries fight each other, then one of them pulls a knife and Big Boss steps in to stop them.
Does this cutscene just happen at a specific point of time during regular gameplay and if not, how do you trigger it?
Best Answer
I think it triggers when morale in low. Spent to much GMP and went into the red without noticing.

All you need to do is replay Mission 11 for a total of seven times.

One thing just comes to my mind, that having staff with the Troublemaker skill might just help here, in addition to having low morale. ;3
