These kaomojis all use a Д character for their mouth while they salute. Some of these look a little more serious, as if they are saluting a sergeant. Others look angry and even dumbfounded. Point is, they all use the same mouth and they are saluting.
These saluting facemarks all use a flat or dash like character for their mouths. Play around with the eyes to achieve different emotional expressions with these flat mouths. Remember to include the saluting arm, though, because that is the important part. Consider adding in another emoticon as the one who is being saluted.
