Wow.
The break up of the Euro could lead to mass rioting and civil disturbances?
Correction.
This is a US Army mission. They have the 173rd Airborne in Europe along with some aviation assets. If anything, you might see a FAST Battalion along with a USMC Infantry Battalion just helping out on reinforcing the embassies. Everything else would probably go to the Army.
The Brits are planning, we need to too!
