1) You can't be detected by the Commander's Scan so think like a ninja when your tickets are low. Like maybe in the 40 ticks area.
2) You can destroy any armored vehicle. How you ask? Quite simple, for Spec Ops vs. Light Armor Vehicles (DPV (USMC), Hummers(MEC), FAV(China))/APCs You can either place 2 C4s at entrances or do what I like to call "Jihading", attatch 2 C4 to a vehicle of your choice- preferably the DPV because it's fast- drive the car near the enemy and either crash into it at high speeds causing it to detonate, or get it within a foot of the enemy and jump out and detonate. If you want to seal the deal and make sure the enemy dies go for the crash method, or get the car bomb close enough and detonate immediately upon exit.
What to do about tanks/anti-aircraft vehicles?
You can be brave and do the above method, but you risk dieing in one tank primary shot. However, if you want to increase your sucess rate, attatch 2 C4 to an APC and it'll take 2 tank shots to destroy you. So in between the time the tank is reloading, you have that small opening to get the APC near it and then detonate.
What about helicopters?
This is a little bit trickier, but not impossible. If someone is whoring the blackhawk (the most overpowered transport helicopter), you can attatch 2 C4 to your lesser transport helicopter and fly near the enemy helicopter, get it within blast radius, and jump out and detonate. This is always a guaranteed suicide because your helicopter will only stay within range for a matter of seconds before the enemy helicopter knows what's up and decides to fly away. However, think of it this way. People love to load up the blackhawk with 6 people, so your suicide kill is really scoring you 5 kills (10 global points), and your team will thank you for destroying the blackhawk menace.
3) Long distance, the only thing that can match the Spec Ops is the sniper. The single shot can be shot very fast with little to no recoil. True, the AK-101 out-damages it, but the drawback is the insane recoil. Use this to your advantage, stay out of sight and just pick people off. They won't even know what hit them, and if you're feeling like a Rambo, you can go in and spray CS:S style and it works. I don't get many headshots in this game, but 3-4 shots in the chest usually drops them.
