Your Platoon Sergeant will order your the move through the obstacle course. (Note: you need to be at the back of the truck and facing it at which time an option will appear in the Action Menu to 'Get in.') You will be driven to the obstacle course. Follow your squad to another 5-ton truck parked just outside the gate and get in. Once you get back sling your file ('Put your rifle on your back'), via the Action Menu. A waypoint will appear to guide you towards the location. The first order you will recieve is to run to a 5-ton truck and back. Keep an eye on the upper-left corner of your screen, were some hints will appear.
The mission will start in front of the barracks on a base. This mission is very easy as it introduces you to Operation Flashpoint: Cold War Crisis. This walkthrough is written for v1.46/ v1.96
