You've come to the right place. Here, I will show you all of the things you need to know in order to have a shot at being as good as the "pros." This post will consist of sections with an instruction as the title, and the following text will explain it.
Get informed!
Many otherwise decent players lack tech-tree knowledge, or a general sense of what damages what how much.

Be aggressive!
Grow a pair and attack already. Stop hiding behind your hardcrete and anti-air and learn to micro.
Keep moving!
Aside from preparing from an attack, your units are not achieving their full potential if they are not doing something. If your opponent has an undefended flank, attack it as soon as possible with full force. Trucks should never be sitting around doing nothing unless the concern is power. Don't forget that trucks can be used offensively to build "defensive" structures in fun and unexpected places.
Have a ritual!
This can be anything unrelated to Warzone, from as simple as putting a pen in your pocket to turning on a laser lightshow in the room in which you are playing. This lets your body know it is time to play Warzone seriously. Laugh if you want, but it really does psyche you up. "I've got my pen and I'm ready to play!"
Stay classy!
Be sure to obtain the ability to build modules through research and take advantage of them. They are a must.
Don't forget research and power upgrades as well. These are critical. You should always be researching these unless you are in grave danger (is there any other kind?)
Diversify!
... but pick a few weapon lines and stick to them. There's no use having 8 crappy turrets to choose from. Make it 2-3 powerful ones. Machine guns and anti-tank are really nice and obvious buys.
Know your surroundings!
Learn the maps. If you're about to play on a map you don't know, first start a skirmish game on it, build a command center, press Shift+Backspace, type "deity," and then take a screenshot of your mini-map - oil will be visible. Simply refer to this screenshot during your real game.
Expand and reconnoiter!
Build sensor towers to have visual dominance over an area. Build hardpoints and hardcrete for physical dominance. Never cease trying to expand, and always take as much space as you possibly can. Seal off those chokepoints with defenses, too!
Communicate!
I cannot stress this enough. Extremely serious players like me take this game extremely seriously. This means using every possible chance in a game to win. Apt communication with your teammates can act as one of these chances - your team can plot research together to shoot for ripple rockets or incendiary howitzers or even something as simple as a factory module. Additionally, communication prevents research overlap which has the potential to be disastrous. Here's how you can quickly let your teammates what you are doing:
The Diplomacy Menur mg bullets
(mapped to F5 / Numpad Enter / Return by default)
- To have your default chat send only to your allies, open the Diplomacy menu and deselect your opponents' comm channels.
- To send units to your allies, select the units, open the Diplomacy menu, then click the tank icon next to that ally.
- To send some power to your allies, open the Diplomacy Menu, then click the bolt next to that ally.
Respect your teammates!
If your teammates respect you and what you have to say and they are not sitting afk, you have no right to abuse them unless they are REALLY incompetent, and then, it's okay. Otherwise, respect your teammates, even if they're throwing all of their units away. Don't exaggerate your self-importance. You're not that good.
Play hard, play frequently!
Can't expect to play well if you're out of form. Duh.
Last, but not least...
HAVE FUN
