Defiant & Anniversary Achievement Help

I am having a lot of trouble with the last few achievements I need to get. I only have 5 more achievements to go and was wondering if anyone one could help by either partying up or giving me some tips if you have already unlocked them yourself.

The achievements I have left are:

Dont Touch That!(Prevent the attacking team from touching the falg in a 1 flag CTF game)- Defiant

Paper Beats Rock (Assassinate a player that just exited armor-lock)- Defiant

All Alone (Be last man standing in an infection game)- Defiant

Emergency Room (Infect 3 player in a single round of infection)- Anniversary

Stick it to the Man!(Stick the flag carrier with a plasma grenade)- Anniversary

Hello

Best thing to do is go here >>> Halo: Reach Achievements | XboxAchievements.com

That site always has people willing to get these extra achievements :slight_smile:

Cheers
