Also STILETT0 , Guerilla (+8 ATK max on infantry unit) and Anti-Armor (+12 ATK max against anti-armor) are always outclassed by Plain Fighting (+20 ATK max for army units in plains).

Gerd von Rundstedt, even though Supply is expensive, you have the alien conquests which quickly make your ace forces no use; and the alien campaigns are pretty long too, around 22 rounds from Union 5 onwards.

Street Fighting stacks with Plain Fighting. When you reach the alien campaigns, you have to fight against sieges to your city by aliens. Rangoon in Union 4 is prone to siege. Tokyo in Union 5 is prone to siege. Saratov in Union 8 is prone to siege. Every alien conquest, there is a siege. When you are in a city, the supply tech you have is the same as having Supply skill, so Street Fighting is a good alternative to Supply (only in 1975 though).
