Digging in the past for interesting threads to displace some spam ...
For me, the largest attack was about 29K aircraft, including hundreds of strategic units, mostly F-32s.
Largest defense was also an attack, but as it was to occupy, it had a large defense including 10k armor.
Raw power of these 40k troops was around 20M (both offense and defense) with an expected 40M counting all boosts.
