A yellow face with its right hand saluting. Used as a sign of respect.

The expression of the face of this emoji can vary across platforms, with some designs featuring a neutral face while others are shown smiling to various degrees. 

Apple and Huewai's designs notably only display half a face, likely to make the saluting hand more prominent when this emoji is viewed in smaller sizes.

Can be considered an emoji version of the o7 emoticon, where the "o" represents a head and the "7" depicts a raised arm in a salute. Variants of o7 remain popular within gaming communities and on platforms such as Twitch.
