When you have a difficult time seeing where your enemies are shooting at you from, send Team Bravo directly in front of you and look which way they are shooting. You will probably lose many men because of their bad aim, but can
always restart the level after you know where they are located to easily take them down the second time.

Turn on your night vision to see all enemies within your line of sight.

During any day mission, if you cannot see your enemies turn on the night vision goggles. The opposition will appear as bright white against the lighter green shades of night vision.
