The Chosen One, the successor of lolcake legacy is here!
With him the new era of nerf allies buff axis shitposts will arrive for the L2P within his have no limits and will expand into infinity and shall be divided only by zero!
Yes, HMGs have additional penalties, but normal infantry shoots at 25% effectiveness pretty much.
suppresses infantry also gets LESS damage from small arms unless they are in short range, that is why despite good DPS HMGs seem to not do enough damage, especially evident with Maxim on longer range.
After some time, defensive suppression modifier is replaced by the opposite of it and pinned squad after short while will get huge rec acc penalty.
You can observe this best, when you use RET volley fire, let them pin a squad and let them work on it, after certain time after the pin they will literally execute the pinned squad.
This is the general idea on how does it work.
For specific values ask your nearest stat wizard.
