In Russia Defender of the Fatherland Day is also a day of all men, so happy men's day! :D
By the way it's curiose that wikipedia uses the word Fatherland instead of more common "motherland". You can see it yourself here.
Ii think it's probably because in the russian name of this day we do use the word what has a root 'father' in it - Отечество - отец = father (there is also a word Oтчизна with the same meaning and root) while мать-земля (mother land - literally) and Родина-мать (also like mother land) have the word мать (mother) in them...
"Motherland Calls!" - the famous poster of the Great Patriotic War, created by the artist Irakli Toidze at the end of June 1941.
