Call of Duty:Modern Warfare 2

I try to do the following, but I'm not sure if they are the right things to do:

1) either be running or be crouching. I try to spend zero time just walking, figuring that I either will be hard to hit because I'm moving or because I'm smaller.

Problem is, when I get into a fight with a guy while I'm crouched in which we both see each other at relatively the same time, he usually wins because he's more mobile and I'm crouched.

2) Call in UAVs while sprinting, so I don't spend a lot of time with my gun out of my hands.

3) Always reload after every little skirmish, even when others are around. Too many times I've tried to kill two guys with one clip, but ran out of ammo at the most inopportune times. Is this the right thing to do?

4) Once I get a kill in a spot, I move. This just seems like basic logic given the killcam, but I'm not sure I couldn't do better by expecting people to come back to find me and killing them again. Thoughts?

5) I try to stick near people on my team, figuring there is strength in numbers, but often I get hit with grenades or bullets that aren't meant for me.

Am I missing any basic strategy? Are these the right things to be doing?

You just made me realize i too get killed alot reloading and i was doing alot better with sleight of hand. So try sleight of hand when playing team deathmatch.

This team deathmatch is different from the past games because you never respawn behind them unless you use tactical insertion. I have spent a whole game respawning in the same place. It's more like teams holding down their side of the map then run and gun. I like to be the flanker myself and what i do is stick to the sides of the map. I have been getting killed alot doing this but once you break past those couple of campers holding down that spot it is worth it. I am about to start using smoke grenades because the maps are too bright and easy to spot from far away. I am getting killed from smgs across the map, even while i am sniping.

It's not always better to move from your spot after a kill in this game. It depends on how good your spot is and if you have a 360 view and room to run from grenades. I have been killed many times from the same guy sitting in the same spot he was in when i was killed 5 minutes ago.

Heartbeat sensor and thermal are a waste until they come out with night maps. Make a ninja class to use in the middle of the match when everyone is getting uavs. Cold blooded, Ninja Pro, and a silenced p90 are my favorite on larger maps.
