Silent, but Deadly

As you quietly wait for the sentry to come close enough for you to slash the living out of him, sweat pours down like a massive hurricane. He is within striking distance. The moment of truth is now. You leap forward and thrust the blade though his heck. Hi is caught by surprise. The ambush is a success.
Confidence is growing with each task. You move into enemy lines and quietly observe what is taking place. You run down the SALUTE observation and try to keep that in mind.
S- Is for the size of the unit. It seems to be heavily fortified with about thirty men.
A- Is for the activity that is taking place. It seems no activity is present. It must be bedtime.
L- Is for the location of the unit. You look around for any
landmarks, but too dark to make out any one thing.
U- Is for the type of unit facing you at this point.
T- Is for the time that you are observing all these things.
E- Is for the equipment being utilized. No motor vehicles are
spotted; a plus. But there is a radar satellite on top of an observation tower.
Time to move in. Dawn will be here soon. You scale over and slide behind a bunker. No one notices you. You hear a military radio in the bunker.
