Dead in the water.. is this how you lose?

I’ve been playing and everything seemed hunky dory but suddenly I’m finding myself without resources to fix broken equipment or refill ammo, and hard enemies constantly rampaging. I can go do a defense but it ends up costing more to resupply than the reward I get.

How am I supposed to get out of this cycle? Eventually I’ll be sending my troops in with nothing but their bare fists. Have I lost??

Stop using explosive weapons excessively so you won’t pay so much for resupply.

Always make sure you have reserve resources. Just like real life, keep some change in savings. Don’t fall into the trap of spending early in the game just because I need that now. Postpone the urge to splurge.
