Battlefield: Bad company 2 Recon class:
When using the SVU, SV-98, T-88 or VSS, it helps to measure out and draw tiny pencil dots on your screen in between the chevrons, for more accurate prediction of bullet drop at long ranges.
Also, when playing HC mode, the center dot will be useful for running around with your pistol, as you can see where the crosshairs would be and aim decently while moving instead of using ADS mode.
The m95 is the only rifle that does damage against Helicopters. It can also break through thin cover like metal easier and still kill the guy behind it. However it has the slowest rate of fire and reload speed.
A GREAT way to take out pesky choppers that are flying too erratically to shoot down conventionally is to get a few snipers with M95's and red dot sights on them. Each shot does about 10dmg, so 3 people shooting it 3 times will leave it with a tiny 10hp left. Works great in HC, where the blackhawk's mini-guns mow you down before you can acquire the chopper for rockets, and also the fact that since the pilot cant see the health of the vehicle in HC and usually only worry if they get hit with a rocket, they wont know they're being killed until they start smoking and it's too late.
At long range the vss will still take 2 headshots to kill, even in HC mode.
The auto spotting attachment will only work at medium range and closer, not at long range.
Wearing body armor in HC mode will prevent people from killing you in one shot to the body at medium range and further. As you know usually it's one shot anywhere for bolt-actions in HC.
Very Useful: The vss and svu are suppressed, meaning they are much quieter, don't show up as a red arrow on the enemy's map (which can still be viewed in HC mode, you just have to pause the game first and you can see red arrows representing enemy firing.) and, perhaps most importantly, they have no bullet wake, the solid-white contrail you see behind the bolt-actions and the semi-solid one behind normal guns. All they can see is the actual round.
As you can see I love Recon class.
