An offensive tip: When scouting, check the radius of the guns and look for blind spots you can sit in. Sometimes you can just ignore entire areas of their base because it's of no consequence to your objective of destroying the headquarters. When doing a pre-shelling of the base, only target the guns that can reach your pre-planned path.
