Got another that's relatively easy.

In the villa stage, take cover near the exit of the garage to the left of the red car - but before venturing past the opening peek out and silent-snipe the guard that's hiding across the path behind the silver, wholly assembled car. If you take him out without making noise, it allows you more prep time. If not, kill him quickly and order your men to cover behind the red car, and you take the position earlier mentioned near the left side of the exit. Your men, as will you, have clear vantage shots at the stairs and garage entrance. What you need to do now is simple>

MAKE SOME NOISE!

Shooting grabs enemy attention. Enemies will always try to flank you, so if you're near the garage and shoot, enemies will attempt the circle around from the outside staircase, and vice versa. So long as your allies are covering you, you can take out enemies by clearing each small wave, running closer to the house, firing, listening for enemy communication, then retreat behind cover (your allies are already covering you). Got to be quick, so be wary of extreme armor choices.

Tons of cover to shoot through in this area as well, and you can plant C4 near the garage entrance to ambush enemies. Works well in a number of ways.

If playing online, mark your targets. If an enemy escapes, they will huddle together. When you see the targeted enemy retreat back into the house, that's where enemies are grouping. Very very effective trick.

Thanks for replying, great tip, might try it now actually
