The off-topic I would like to explore is triangles.
Illegal or off-grid enclaves, safe areas with three way movement of clandestines/contractors.
One large such triangle is al-Tanf.
Syria, Jordan, Iraq.
This has been a safe area for terroists/contractors to operate out of.
Supplies and services can move from safe pair of hands Jordan, although the King of Jordan is currently getting jumpy.
Islamic State/contractors several times have attacked Palmyra both the ancient city and the modern city as well as the Israelis and others continually missiling T4 military airbase.
Shenanigans are ongoing.
