Kilroys 3/3
1. As you enter the windmill area there is a small shed on the right which has the first kilroy on it.
2. Your objective requires you to clear the Farmhouse. Head up stairs and into the bathroom. On the wall on your left as you enter there is a Kilroy. Simply enter the bathroom and walk to the window, then turn around 180 degrees to exit the small room and you'll see it.
3. Before you enter the crash site area and in the area where you first control two fire teams there is a shed on your right just before you cross the road to enter crash site area. Look into the shed through the window to find the Kilroy.
