Hi, I guess I posted wrong for questions about beyond the call of duty, just wanted to see if could get help on how to kill the 3 gaurds in the street as well as inside the zoo. I have been killing from the back out toward the front entrance, I have spooky working as the zoo keeper but would like to get the other guys inside. I thank you in advance, RudyMan

The spy as the zoo keeper can kill the tigers, they won't attack you. So the green beret can join the zoo the tiger cage.

The guards at the entry can be killed at the end of the mission, when you have to get the driver to the truck.

So just kill the guards around the house in front of the zoo, an then the guard to the left, there you can climb up the wall. The spy can enter the zoo through the front entry. Green beret + spy are the dream team. The driver only has to the drive the truck. The three men patrol and other patrols only have to be distract for some time with the spy. You don't need to kill them.
