any suggestions for halo 3 two for one achievement?

[chrisxchan]

ive gotten every other achievement legit
including perfection, but this last one is giving me problems
im rank 40 in lone wolves, so im too high for people to fall for it
and ive tried asking, but everyones too worried about losing their rank that high
and i honestly dont blame them
so im pretty much stuck
can anyone offer suggestions on an easy way to get it?
or more importantly, can anyone help me get it?
id be more than willing to return the favor on any mutual game


my gamertags chrisxchan if you need it

you can wait for a map with a ghost and just wait till it gets borded and kill them both or you can just wait till two guys run at each other with ars thats how i got mine this one was real tricky and took me numerous trys to get

I would just wait until i saw two guys fighting. I tried to lure them, but it didnt work. Finally one day i was about to laser a guy in front of me, when a ghost and a mongoose crashed into eachother behind him. When it was charged up i ended up getting all three people, and i got a triple kill.
