Only some 1 million Ukrainians are in all regular and irregular armed formations combined, including police.

For some reason you have this silly meme how they sent every man "to the east" (the main theater used to be in north, now is in the south), but it's a not WWII style mobilization. For most of them the contribution to the war effort is still doing their regular jobs, including farming without which Africa will starve like Moscow made the Ukrainians starve in the famine of 1933.
