Sarski

Okay...do I call Charlie Sheen, Clint Eastwood, or The Duke?

That isn't such a tough decission to make.

Seriously, though, I'd send whoever is closest and ready at the time, and given the reach of SF throughout the world makes them prime to be just about near or in the hotspots already, go figure.

Of course joint operations, and multi tiered operations could be in line as well.

One of the martial tactics of old Asia (Japan, China, Mongolia...) was for the experienced warriors to hang back a bit on the battlefield and watch the subordinates fight it out with the enemy. This way the more experienced could buy a little time to asses the enemy more accurately and also determine who on the battlefield was the biggest threat. Then they (those who were hanging back and assessing) would go into battle.

It of course cost the lives of those with less experience, but probably not as costly had all been engaged without understanding just how things were developing on the battlefield.
