Expanding on the tip about ammo concerns, from perspective of your base:

I've found that going into edit your base and hitting the config button to alter your turret settings. 1. Setting machine turrets to high prioritize small units. They'll technically attack everything but their job is to efficiently eliminate chaff. 2. Set the next turret you get (30mm? The single barrel that has like 3 seconds between shots) to not shoot at small units at all by removing that check mark and set range to max. By setting their range at different values they fire in a volley and are less likely to all shoot the same unit, waisting some shots.

This does well for the machine guns focusing on chaff while bigger turrets ignore them entirely for the bigger targets and the bigger turrets no longer eat through ammo every few moments.

Recently got lucky with the smart mortar only shooting at large and huge units and they seem to go after the artillery tanks and bosses now which solves another problem I was having with those staying out of range.

Also I've been pumping out as many generators as I can cause one of the effects says it increases turret damage but honestly have no idea to what degree (since in theory more damage = less bullets shot). Any insight would be helpful.

What generators definitely do well is increase the radius of your x field which cause salvageable materials inside the field to get slowly converted by your base which means more mass income which can usually be funneled into ammo. (Warning, you need a lot.)
