The difference maker, for me at least, is the type of scope you use. Use a save that has a good deal unlocked, if I'm recalling correctly that you can pick your own loadouts. It's been years so I'm not quite positive.
Use a thermal scope. Just make positive of that. You can see through walls with that. If you attach a FMJ, your weapon will deal slightly more damage through cover too. Those 2 combined, and stay in cover whenever humanly possible, and you can just potshot enemies without them even being able to see you. Make it a weapon that can take out enemies in one shot, like one of the heavier sniper rifles, but also make sure you keep up your ammo for it. I would always take along a big powerful LMG too also with a thermal scope, not just for when I needed it but also because I sometimes used it for the same purposes if I was otherwise low on ammo.
You might be behind the same piece of cover for maybe 5 minutes at a time, not sure if you can advance because maybe the second you do someone you misses erases all your progress. So it's boring. But it's definitely do-able and a lot less stressful that way. Grenades can still be a factor so just hang back.
