Definitely rushing. Put a decent SMG or assault rifle in my hands and I'll go crazy, toss a few nades into the mix and I might wipe out a small village.
I'm actually a good sniper because I have decent reflexes but it bores the crap out of me. I'm at my worst when I have to be quiet, sneak around, plant traps (I get bored after about 30 second of waiting for someone to spring my trap).
CoD4 I always went short/medium range and ran around like crazy, smokes were essential to my kit and endurance.
CS:S I'll blast heads off with the assault rifles, MP5 or if I'm feeling evil the TMP (it's just too easy to get a headshot with that gun).
The Battlefield series never really clicked with me because there isn't a lot of close combat but I usually drove a vehicle into an enemy base, jumped off and started shooting people as they ran around trying to accomplish a goal unlike me...
