Why are my Garage and Airpad locked?

I bought the game at launch, played through campaign, and then got caught up in the other aspects of life, and now as I’m trying to play the other game modes, the game won’t let me build the Garage or Airpad, and the game mode where you start out with one of each, all of the units inside are locked. What gives?
How do I fix this?

Certain missions allow you to build these buildings while others don’t in the campaign. In multiplayer modes, you are required to have a certain tech level (base upgrades give tech levels) to build airpads and vehicle depots. In Deathmatch and Domination you are required to have tech 2 in order to build them. In strongholds you are required to wait the allotted time in order for tech 2 to be unlocked so you can build the tier 2 units out of the respective buildings.

So your most developed base determines your Tech level? I was going for quantity of bases, wandering why my Tech level was stuck on 1.

Just have to save up 1000 power and upgrade the main base to get to tech 2. Then another 1500 power to reach tech 3.
