From the room you start the mission in you'll see some stairs next to some oil drums. You need to climb up these and then enter the room on your left. In front of you, there is a desk with some papers on it (next to an empty shelving). Stand in front of the desk and press X to activate this recon point.
2. Irish Guard
Once you are ordered to clear the upper floor of the warehouse/factory you'll come to an upper floor walkway that joins the two buildings together. It's part of the mission objective route and so you can't miss it. Once in the middle of the walkway there are some bits of debris on the floor. Here is where you need to recon.
Kilroys 3/3
1. In the first area you start the mission in, once you are required to secure the ground floor - this is after killing the gun operatives outside and when you see the tanks moving down the street. From the hole in the wall (where the gun emplacements are) head north through the door and you'll walk into a flooded narrow area. Continue to the end and the Kilroy is on the wall in front of you.
2. You are then required to clear the top floor of the warehouse. You'll get a short scene as you and your team go up the lift. As soon as you resume control head to the doorway towards the west. As soon as you enter the doorway turn right (facing north) and you'll see the Kilroy on the wall.
3. Your next objective will be to clear the roof. Once you resume control after the cutscene, from behind the sniper who is on the PHILLIPS sign, kill him without getting near and then stand beneath the first "PH" in the word Phillips (without actually standing on the platform), and face North. From here walk as far North as possible, then went you reach the wall face East. You'll see the kilroy in front of you. NOTE: DO NOT TRIGGER THE SCENE OTHERWISE YOU WONT BE ABLE TO GET THIS - SO DO IT FIRST BEFORE WALKING ONTO THE LETTERS PLATFORM.
