V - This is at the beginning of the level, once you jump in the area with the first two scorpions, turn directly around and look on the ridge behind you. Grab or keep the sniper as you will need it for the next Target Mark.

C - This a bit hard to spot, it is on top of the volcano river in the second area of the mission. You need to get it using the Rifle and it can be a bit tricky to spot. The best spot to go to is next to the VS on the freeway and snipe it.

O - This is in the lava fall to your right at the start of the third area. You can hop out of the VS and stand on the edge where you can jump and shoot with the machine gun.

N - This is under the storage unit with the good VS in it in the third area. Supply unit is on the lower west side of this area. The easiest way I got this was to take aim using the Rocket Launcher.

L - This is in the room you enter with the two VS's that are attacking you, it will be on a ledge upwards to your right (to the south on the radar). Hovering and shooting with the VS is one way to hit it.

A - This is on the left hand side when you enter the room with the big circle on the floor. It will be under one of the lower platforms along the small river-like thing with lava in it. Just anchor off an edge and slide down to see it under the platform.

O - This is easiest to see from the room just past the one with the L in it. Go to the center and look to the southwest, it will be high up on the framework. The easiest way I got this was to take aim using the Rocket Launcher.
