Ho is a character from Splinter Cell: Chaos Theory.
Not much is known about Ho other than an email that was sent to one of Ho's partners Feng. The email was about Ho catching one of Feng's mistake which said that the other day he noticed that Feng had orderd some NATO 5.56 ammo but they couldn't use it because it isn't the type needed for the amunitions. Feng came across this in the small arms munitions in the warehouse of their base. This type of ammo happens to be useful to Sam Fisher.
