How should you organize your Modern Warfare 2 gun custom cles?

I like to base my cles on real life tactics so in the game I can take on any situation. I organize my cles by types of warfare(Fortification, siege, Guerrilla, Attrition-Wearing down the enemy, Reverine-conserving amo with accuracy, and Counter). This helps because if you have a cl for these situations you can conquer any in the game. I kind of lied. I used to use that but it had some weaknesses, however this one does to, but nothings perfect. Both have their ups and downs. The stratigy I use now is making my cles based off of different special forces around the world. It relates more because the game has the guns they use. I use certain special forces but you can pick your own and custumize your cl to fit them. You want diversity so that you can pick the special force you want and think is right for the job and use it, plus this works for anyy map. Example: One of my classes is Navy Seals and I use UMP with a silencer and a AA-12 with a grip, and my perks are 1. Marathon or scavenger. I use marathon 2. Lightweight or Cold Blooded. I use Cold Blooded. 3. Ninja, Commando, or Sitrep. I use Sitrep. Now you see that i'm like a seal, a guerrilla fight, silent, strike fast and leave fast, and most of all I can kill like one. I'm not going to tell you what guns to choose because it's a waste of my breath, you can't just get used to a gun and go right back to another and pwn with it on Q. You choose your guns just try to put them in diverse categorys so you are prepared for any situation, see you on the battle field.
