True for field ops, but isn't sleeping in a car with VIPs on a way to a event dinner disrespectful?
Plus its a vip event and you're gonna end up with a just awoke shit face when you arrive.
mostly a skill Issue, hate to say it but with enough practice you can sleep for 2mins and no one will ever know. I recommend forcing your heart rate to spike to quickly awaken yourself
It actually isn't falling "asleep", but entering that halfway point where you are just about to lose consciousness. I did this all the time during my service years, and still take advantage of it for quick "naps" in my older age.
