"United States Army Schools" badges

[Panzerpionier]

Hi folks

What are these badges intended for (instructors, alumni, graduates...)?

They seem to be composed by the shield of an US Army School placed on top pf a common back "shield":

US Army Military Police School:

US Army Infantry School:

US Army Ordnance School:

Thanks in advance

I believe they are given to foreign graduates of US Army schools. Here, for example, is the current Chief of the Defense Staff of Estonia Colonel Peeter Hoppe. I knew him when he attended the Infantry Officer Advanced Course at Fort Benning in the late 1990s.

Thank you very much for your help - Sorry for the late reply.

It seems that both the "big" and the "abbreviated" form are used by foreign graduates:

Each picture corresponds to a different Spanish Army officer graduated from the United States Army Field Artillery School.
