Where on your Pilot's body can you see your Titan insignias?

I originally thought that insignias only showed up on Titans. That was until I was playing the "The Battle of Demeter" campaign mission as IMC. When we were falling in the drop pod, I looked at the other Pilot in the pod with me and noticed that on his head was the Bonehead insignia (the white and red ram skull).

So, that must have been his Titan insignia. In that case, where else can these insignias be seen on the Pilot's armor?
