First off, let me start by saying, what works for me, may not work for you, yaddah yaddah, not responsible for any damage to property when this tip/guide thingy is used.
Now that's outta the way, here is the tactic that i use in most Port Valdez Rush matches, and it usually ends in a victory! I've only tried this with 1 person (me), but with a squad working together i imagine the results would be devastating. When its a semi- noob trying it take some practice!

1st off all, make sure your equipped as an assault class, with one of the "all kit" weapons, wih EXPMK2 (i think its called ) and the EX upgrade. Depending on what you want, either V smoke, ALT weapon or VWARHD.

1.Parachute down to the T90 MBT and drive to A. Avoid the main road, instead go down the verge with the wooden fencing and start shooting the building which has M-Com Station Alpha inside. Make sure at least 3 of the main walls are gone, or enough to collapse the entire building. Once you hear that creaking sound of a building falling down, go to Bravo, being careful to spot any AT mines.

2.This is where the c4 comes into play, use the smoke launchers on the tank if you have it, and deploy all the C4 you have and then arm the charge. Get back in the tank, go to a safe distance and start shooting at the m-com station. With any luck the C4 should blow and you now have a very weak and armed M-Com station. It helps ALOT at this point to have a decent gunner, to get rid of any of them cheeky recons with C4, aswell as the BMD IFV to keep them busy and an engineer. If you're a gunner, keep an eye out on those stationary at's. One is on the construction building, on the right hand side, another behind some concrete blocks next to the house. If you can keep them busy until the station explodes, then brilliant, you can move on! If you get killed/blown up/raped by a sniper, and the charge is defused, 4 more C4 and bye bye bravo!


I'll try and get more posted for the second area of Port Valdez soon
