Both games implement some combination of or have variations for each of the following features:
- Scope sway
- Gravity induced bullet drop
- Bullet travel time
- Body posture
- Clothing (Ghillies)
- Tools
Battlefield:BC2
Scope sway
None. BC2 does not implement a "breathing" aspect for sniping. Thus your crosshairs are stationary unless you move them.
Gravity induced bullet drop
Yes. As range to target increases the actual point-of-impact of your round with relation to the center-point of your crosshair increases.
With very long range laterally moving targets you have to put their torso in the lower-left/right quadrant of the scope and fire to get a hit.
I feel that it makes stationary target sniping ridiculously easy compared to MW2, but makes it harder to hit moving targets.
Bullet travel time
Yes. You must lead targets that are in motion.
Body posture
You cannot go fully prone in BC2. You can only kneel.
Clothing
Snipers wear ghillie suits. Their utility can be limited since they cannot go fully prone. It is still useful in large bushes and trees though.
Tools
There are no thermal scopes, heartbeat sensors, AC-130's or other anti-sniper elements in this game.
Call of Duty:MW2
Scope Sway
Yes. MW2 implements a "breathing" aspect for sniping. Thus, when completely stationary your crosshair will bob semi-randomly.
You can also "hold your breath" for a short amount of time which reduces the movement, though not completely.
Gravity induced bullet drop
None. Whatever is under the center-point of your crosshair when you pull the trigger is what gets hit.
Bullet travel time
Yes. You must lead targets that are in motion.
Body posture
You can go fully prone in MW2. This decreases scope sway and makes you harder to see.
Clothing
Snipers can wear ghillie suits. The suit must be unlocked. Different camouflage colorings can also be unlocked.
Tools
As a sniper you can unlock a thermal scope which makes sniping super easy-mode.
However, you are also terribly vulnerable to things like AC-130's, Harriers, etc. unless you are using cold-blooded.
The SPECACT parts were added together with a DLC, the SPECACT Assault, Engineer, Medic and Recon individual DLC's, as well as a bundle DLC that included all four.
The SPECACT DLC for a particular class gave you an extra weapon, basically a "SPECACT" version of one of the better weapons for that class, unlocked and ready for you to play with. It also gave you a "Kit" which is basically a different Camo-suite for you to wear.
On the menu, after installing the DLC, you can select either "Assault" or "Assault+" class to select which kit to use. The weapon is available to both classes, but not all game modes.
For the four classes, the weapons are:
- Assault: M16 SA
- Engineer: UMP SA
- Medic: MG3 SA
- Recon: M95 SA
The excellency pins are awared for reaching a kill count of 8 in any round with the specact weapons.
The efficiency pins are awarded for reaching a kill streak of 5 in any game round with the specact weapons.
The Insignias are awarded for reaching a total kill count across game rounds of 100 with the specact kits.
On Xbox 360 and PS3, there are achievements and trophies that are awared for getting all 3 awards (excellency pin, efficiency pin and insignia) for a particular class. On Xbox 360 these are worth 15GP apiece.

It's a quite notorious weapon, and like the Grenade Launcher Attachment (a.k.a. Noob-Tube) in Modern Warfare 2, quite deadly against infantry. Since it does not lose elevation, you can snipe anything from the far end of the map, if you know where to shoot.
So, beginners, as they get hold of the weapon, abuse Carl Gustav, and get on other people's nerves. This causes imbalances in some people's opinion, yadda yadda, so they, as admins of their server, forbid the weapon as a rule.
It's a subjective issue and there is no scientific reasoning behind it. But I sense it has to do with getting killed by a weapon which requires no aiming skills whatsoever.
