No they don’t, the inaccuracy was removed since ESOC Patch and subsequently ported to the release version of DE.
ChuKoNu still miss shots ，miss the second or the third cross。
Skirmisher and ChuKoNu have same damge ，26 chukonu always can not kill a MeteorHammer when 26skrimishers kill it
thats due to the multishot mechanic i think rather then shot inaccuracy, other mutishot unit have the same problem
