Ok these are the pros and cons imo of elite force units after playing with them a bit
Pros
-can spawn any unit as long as you have the required building for it. Level doesnt count(i.e you can spawn a tiger in a lvl 1 city that has a lvl 1 factory)
-decent mobility, usually a bit faster than standard units(except for the gustav and tiger)
-unique skills although they get hindered by the upgrade system
-insane defense. The weakest infantry unit in terms of defense has the same as a max tech super artillery
-not expensive in terms of money. More cost efficient than triple or even double stacked units(depends on units)
-you get better results having general on special forces than standard ones(titles help such as guderians)
-really versatile. You can have a tank that acts like an infantry, a medic unit, a transporter, a tank-like artillery etc
. Cons
-can only build once(air units are different but theyre still limited)
-no ranking system
-pretty expensive in terms of tech
-tedious upgrading system
-some abilities aren’t available/arent at full use due to more upgrades being needed
-some skills are kind of mediocre(HMS Wales specifically the sea mine spawn,M7 Preist and Bradenburgers)
