In all honesty, I would be more concerned about availability than someone breaking the encrypted data. Especially so if this satellite provides mission-critical support for the warfighter.
I know that body language and customs are different, but I wanted to point out that in some Asian cultures, arm-crossing is done as a sign of respect, especially towards elders. It's a source of confusion and amusement for older people when the Western-integrated young people get angry.
That said, one should keep an eye out for more than just nonverbal cues, as telling as they may be.
Another good remedy is an oral appliance for sleep apnea. I use one to position my lower jaw forward while I sleep so I can breathe more easily. The appliance is also a lot easier to maintain than the CPAP (an occasional brushing will do it good). The downside is that it can cost a lot more than the CPAP, as in several thousand dollars.
Edit: I used to use CPAP, but I found fitting it on my face to get a good airtight seal was finicky. It was only after using the CPAP that my insurance let me consider the oral appliance.
Someone should do a mod of that, based on characters from the old A-Team TV show, complete with the original theme music. The "build defenses" interval would be like the build weapons montage.
