When you start your objective, and a few of your men die, the game prompts you to press A to load from last save. Then it asks you to press B to begin a replay at last save point. Press B and you can fast forward the replay. Just before your men die on the replay, press Start. Scroll down the pause menu and select "Jump into replay". Then, stop your men from entering enemy territory.
This trick will help you through most of your missions by marking your enemies. Press Black to bring up your GPS at any time, then press X. You will hear a woman's voice, and after about a minute she will mark the targets on your GPS. Be very careful, as there are some people that she cannot find.
