Yep, he's talking about that shoulder blood type placard.
Medical Info is probably what it's called. Blood chits were worn by ww2 pilots and most popularized by the flying tigers in china. Those chit had a note written in chinese or the local language informing the local that the downed flyer was friendly to his cause and to take care of him and they would be rewarded for their efforts.
This shoulder sticker on the other hand has just medical info. Blood type, serial no. and rank and allergies would be the most appropriate things to put on it.
This began with the modern soldiers duct taping their blood types to their boots. These days they have specialized velcro patches with blood types that soldiers can just velcro onto their uniforms

Most troops now days also write it with marker on their boots, usually on the top around the opening. Troops will sometimes also have it on their helmet along with their roster number.
The blood CHIT is still in use today as an way to provide aid to troops seperated from their teams.
The "Blood Chit" has been in use for over 200 yrs. But only really got much use in the last 100 years starting in ww1. I found this article from the USMC Heritage Press http://www.usmcpress.com/heritage/blood_chit.htm
