Elite in less than no time.

Well, I am not sure if this has been posted before.

If you do the glitch with the unlimited spawn-dudes (got to get rid of update for this).

You should stand close enough to the spawn point to get C.Q.B. aces, get quite a few of these points, depending on your current rank.

Then if you think you have enough.
(I did it from Sergeant First Class and got like 12000 C.Q.B. points.)
You just update (and get the expansion-stuff if you haven't got that already) and VOILA! You level all the way up to Elite.

This is because the expansion lets your A.C.E.S. go all the way up to level 100 and every level is worth 5000 EXP-points.
