I find upgraded raptors are really good now.
My setup on normal at level 50 was mostly raptors, guardians and arty. Some hydra allows the raptors to hit air. Main gun was the minigun with cleaver as secondary.
Medium size i had full strikers and 1 aegis, no sams. Large was 1 decimator.
Abilities were shield boost with only cooldown upgrade and the time stop.
Didn't lose a single battle and boss died really fast.

Played the game and won by utilizing airforce. I think it is a different strategy to yours but i think its viable

first play: normal -> 75days win
second play: brutal ->75days win

Tactics:
reforge the following weapons to X
primary: punisher...the other ones are bad, they dont do damage. punisher is god for taking out high priority targets within one reload. maybe disintegrator isnt bad but i couldnt make use of it
secondary: destroyer...no need to explain, best nuke

abilities: time warp and shield only. flare and volley taken at the last minute to take on the boss

Defences:
cyclone: OP capable of taking on both ground and air units
spectre: need it to eliminate swarms of infantry
guardian: well, i dont think i need to explain how important they are
ranger: we need volley to take down the boss
Aegis: no need to explain
SAM: well, theres nothing better to place. our cyclones are not capable of taking on max difficulty air raids so it comes in useful
decimator: i find it more useful than the obliterator because the obliterator misses its targets quite often


How to win:
1) rush cyclones because one cyclone and your punisher is the way to get through the early levels.
2) upgrade punisher to 4-5rounds so you actually take enemies down quickly
3) set up 1-2 guardian commands so that ur not so vulnable to infantry
4) set up an army of cyclones and reforge punisher so it can one shot infantry at the very least. start with taking the hexas on the outskirts of ur commanding zone, so it will last longer
5) at this point, u should have a good enough army to withstand most enemies. keep building cyclones until your outskirts of the hexa are all cyclones
6) go get ur destroyer, aegis, spectre, SAM and reforge punisher and destroyer to a decent level
7) by this point, it should be something like day 50. you can get close to beating the boss but u probably dont have enough firepower to actually defeat it
8) keep building; fill ur spaces up with cyclones and spectres and the necessary infanty
9) thrash the boss on day 75

HAVE FUN!
