Commander is a rank exclusive to the Navy and Coast Guard, whereas Major is used by the Army, Air Force, and Marine Corps. Commander is pay grade O-5, which is equivalent to a Lieutenant Colonel in the other branches. Major is pay grade O-4, and is one rank lower.
A Navy Commander has a higher military rank (O-5), than an Army Major (O-4).
Higher - very much so. The Corporal is the commander of a Rifle Section - about ten men. The General is (at least) the commander of a Division - four Brigades - though there tends to be an inflation of rank at those levels, i.e. unemployed Generals, who can still issue orders, but shouldn't.
If you do ranked races and do well you will be ranked a lot higher, if you do bad you wont rank as high. So do ranked race and you get higher in the ranks.
The Intercontinental Championship is higher ranked than the US Championship.

There are two requirements to level up in Halo 3, Skill in a ranked playlist, and experience points, or EXP. It is a multi-tiered system in which a player gains rank by getting a higher skill number in a ranked playlist. To get a higher skill number, you must win matches in that particular playlist. In addition to skill level you also need experience points. Experience points are earned by winning an on-line match, be it ranked or unranked. The way they tie in together is that you can get promoted to a higher 'tier' (meaning captain, commander, general) with skill number. You can gain rank within that tier with EXP (captain or staff captain; commander or strike commander; 3, 4 or 5 star general) . That being said, for the higher tiers you will need a certain amount of skill AND EXP before getting the promotion.
