The winding road that led Psycho and O'Neill toward the VTOL was the same road that would lead toward the harbor. O'Neill climbed aboard the VTOL to provide air support, while Psycho began to rush toward the target on foot. There were no working vehicles left in the area after the battle with the KPA.
Psycho reached a road block, staffed with KPA troops. Using the silencer and the sniper scope on the submachine gun picked up at the last way point, he was able to cap off the outlying troops.
One of the KPA likely radioed for help, because an armed helicopter was heading in his direction. So, Psycho switched to his rocket launcher and fired two shots directly at the chopper as is began to fly over.
The helicopter was destroyed and by the time it hit the ground, Psycho had already dropped the launcher (with one rocket in tact) and headed back to a supply crate to pick up another fully loaded rocket launcher. Psycho thought having three rockets might come in handy when he finally reaches the roadblock up ahead. After destroying the helicopter, everyone from the KPA was aware that Psycho was on his way.
He reached the roadblock and noticed a stationary machine gun at the heart. Also, there was a guard in a watch tower yielding a rocket launcher of his own, as well as troops stationed on top of transport trucks.
Using the SCAR equipped with a silencer and sniper scope, Psycho acted more like me (Nomad) and used stealth to quickly move into the area unnoticed. He flanked the outliers from behind and took them all out with a single shot - including the guard in the watch tower.
The last two remaining solders were on top of the transport vehicles, which he opted to take out using the KPAs own stationary machine gun.
Psycho then hijacked a Hummer and raced toward the Harbor. He had to make up time for the delay encountered at the roadblock.
When he reached the harbor, Psycho used a KPA FY71 to force the throttle down on the Hummer. Then, he jumped out of the Hummer while it raced toward the guards at the gate.
Up above, O'Neill was providing air support. The harbor had been reached. Now to figure out what can be done to stop that sub from leaving the dock.
