I also maintain that Chrome is weaksauce, and IE9 is fast and works very well
It is practically impossible to skip Sergeant. The first rank that is possible to skip is Gunnery Sergeant Grade 3. That is because the required experience for Lieutenant is 70 and Lieutenant is the first rank that requires a skill level (of 10) to achieve.
Basically even if you were a 50 with 1 experience (this is an extreme example!) you still couldn't skip Sergeant, because the experience required for Sergeant is lower than the experience required for Lieutenant. You would achieve every rank all the way up to Gunnery Sergeant Grade 3 (non inclusive), then it would go:
Lieutenant, Lieutenant Grade 2, Captain, Captain Grade 2, Major, Commander, Colonel, Brigadier and finally General (and Grade 2, Grade 3 and 5-Star General).
Anywho, I'm not sure how you have managed not to receive the UNSC Spartan achievement. It may have something to do with the update that added playlist experience (such as the Lightswitch and Spartan Officer achievement glitches).
As ARBITOR suggested you could try contacting Bungie, although I believe they cannot activate the achievement for you. It's worth a try though - they may be able to tell you why this has happened at least.
