I have the 2 tm manuals for USMC colors and markings
contrary to popular belief everywhere I was actually shocked when I read through them, that their vehicles were marked fairly well for what we percieve as markings... So much so that when I mention this to some an all out argument ensues over it- until I show them the TM.
corp vehicles
started with division/battalion/company/platoon markings in 1943 or 44 I think.
*been awhile since I looked at them *(according to USMC SOP for equipment ID) It was then up to each Battalion CO then each Company CO down the line to decide what got marked and how, hence all the diff markings we see or lack of.
The manuals are large and are of the most recent update sometime in the 2k
range, however when reading through you can see how the markings have changed very little if at all since the original decree, if you are familiar with the Corps break down from division level through squad you already know it is very simple, and complicated at the same time, they are unlike any of the other branches of service. Hope this makes sense.
Let me know if you want a copy and I will give it a shot sending it to you. or maybe mail you a copy if i cant email it..
And you can mark it up how you like
