I'm not very good with words, or helping people, so if you can gather anything from this guide is that you don't need to be smart or even have a normal brain to get kills with this method.
FOLLOW THE STEPS TO THE LETTER OR YOU WON'T GET ANY KILLS

So.
If you have read past this line then let's get onto the materials needed to actually success with this.

Available for the entire VC team is the SKS. Now you might be one of those people that won't touch anything else than 30 round 7.62x39mm glorious automatic long piston Avtomat Kalashnikova, but this is essential for this method.
Why I chose the SKS instead of the AK-74U is simple; This weapon has an extremely similar noise to the M14 and it one hit kills (as much as a weapon can one hit kill in this ♥♥♥♥♥♥♥ game). Extremely efficient for flanking and it's always available, plus, even if in real life it shoots the same round as the AK, in the game it does more damage because in the early ♥♥♥♥♥♥♥ beta those ♥♥♥♥♥♥♥ united states babbas found that getting killed by the AK more than once per match was too much, so after so the ♥♥♥♥♥♥♥ DEVS NERFED IT TO DO LESS DAMAGE THAN THE ♥♥♥♥♥♥♥ M16. The M16 might not be actually stronger, but it feels like it.

It's the only material needed, apart from a computer that doesn't stutter too much, if possible.

Whatever, just pick the ♥♥♥♥♥♥♥ SKS you ♥♥♥♥♥♥.

Before you get your mittens onto a nice chinkshit SKS, you must pick a TERRITORY server. Not gonna explain why, ♥♥♥♥ off.

After that you must find a nice, hidden spot, preferably on the first few capture points. This can range from the tunnels in Hue City, the no collision trees' bushes in Cu Chi or the bushes infront of B in Hill937 to the left flank.
I assume you don't have much brain matter to get there without getting killed, so you you gotta get there before the US get there. What I mean is that you get in your hideout, defend it for a while or alt tab, and when the US capture the caps near it, they will spawn behind you. If you go there after the US cap the points near it you won't be able to shoot, but if you get there before them and wait till they get those caps you will be essentially behind them with a weapon that sounds exactly like a M14 and you WILL be able to shoot.

So, find a nice hidden spot, wait till the US advance then start shooting at them from behind.
AIM FOR THE HEAD WITH EACH SHOT IF THEY ARE WITHIN 30 METERS OR LESS, OTHERWISE THEY WILL SUSPECT THAT SOMEONE'S BEHIND THEM AND KILL YOU WITH THEIR ONE SHOT M16

Example:
Then the US capture C:
And then you get easy kills.

Cu Chi, infront of E.
You can get inside the tree, it's actually slimmer than it looks.


Cu Chi, the roof you can drop off from the main roof of the building of A.

These spots have had about 20 seconds of lifespan for me, but I bet you can make it work better.

So that's it. If you get killed while hiding please do comment, because so far that hasn't happened to me :').
