Look at the map and fallow the red line slowly and be sure to look out for any possible enemy presence.
+1, but also
Grab a pen so we can mark things on the map later
You decide to take a pen from the nurse just in case there is anything important to mark on the map.
Next you decide to follow the red line on the map. It leads you through to a fire exit not too far down a hall from where you picked up the map. After descending the stairs, finding sever bullet shells on the ground blood splattered on the walls and bullet holes all around, you enter the ground floor. The sight nearly sickens you, there are half a dozen bodies down the main hall as well as more in the rooms attached to it. The floor has many large pools of drying blood. There doesn't seem to be any enemy combatants still in the building.
You continue further and find that the main lobby, past explosive breached metal doors, has another dozen or so dead bodies. These bodies are in fairly normal business attire as well as military uniforms and nurse's clothes.
Here you find two dead armed guards. After checking their bodies you find two handguns. They are standard Rus' 9mm sidearms. After checking the magazines and clearing the chambers, you reload and chamber a round into one of the guns leaving the other in your bin. You also decide to take one of their pants that are undamaged and fairly clean and the other's light vest which does have a couple holes in it but it is better than nothing.
You hold the side arm in your hand with a full 12 round magazine in as well as a round in the chamber, the spare magazine in your pocket has 9 rounds in it.
You exit to the parking lot to find several destroyed cars, a military transport with little damage, a few more dead bodies, and plenty of skid marks leading out of the parking lot.
What do you do next?
