No, because I'm not a pussy.
Yes you are, you use Commando Pro.
I have two main classes, that I tend to keep in slot 6 & 7.
6:
UMP.45 w/Silencer
Any pistol with a silencer, or the Spas-12 w/ Grip.
Marathon Pro
Cold-Blooded Pro
Ninja Pro
Throwing Knife
Smoke Grenade
7:
Intervention w/FMJ
Akimbo Magnum or Spas-12 w/ Grip
Sleight of Hand Pro
Stopping Power Pro
Ninja Pro
Semtex
Stun x2
-Some classes for the AR and LMG:
ACR w/ACOG
Magnum w/Tac-Knife or Spas-12 w/Grip
Sleight of Hand pro/Scavenger pro
Stopping Power or Hardline (SP isn't needed on AR's as much as people think. If you hit in the upper-body to Head, you'll kill just as quickly thanks to the health being that of what Hardcoire had on CoD4 in Core on this game)
Steady Aim Pro
Frag
Stun x2
LMG:
RPD w/grip
G18 w/anything (it's good to have a quick-firing gun like this for CQB, I would suggest a Shotgun, but the RPD acts as a long range shotgun, to be honest)
Sleight of Hand Pro
Anything. Stopping Power makes this gun a fully-auto version of the FAMAS or M16, killing in 3 bullets for most targets.
Steady Aim Pro
Semtex
Flash x2
I tend to just make every and any class I can when I get the chance. My K/D is dropping, though. It went from 2.15 to 2.11 in the past few days. Letting a 6 year old play it wasn't a great idea, though.
Also, I played some guy who was bragging about coming 4th in some MLG tournament the other day. I told him to shut up, so he invited me to a private match, FFA, Sub Base. Just me and him. I started 0 - 4. I thought he was pretty good, he was using the UMP, so I switched to my Intervention and hit a 5 KS - called in my Predator, got him as he spawned. He ran in to the building with the stairs leading up, and the open roof-top leading to the other building. The usual campers spot.
I picked up his UMP and rushed in, sprayed like shit, got my Harrier, called it in, and he ended the match to start calling me a faggot.
Either this guy was a lying sack of shit, or the tournament he was in was filled with people unable to shoot.
