Unknown ROTC/ Military Academy patches

[no12sabe]

I've been cleaning up the books and still don't have an answer for these suspected ROTC/ Military Academy patches.

 

I found a mention in the ASMIC Facebook of the Dallas Independent School District, they used the Yin-Yan design with the school colors. It mentions the George Washington High School as the possible ID for the purple and white one below. A review on the Institute of Heraldry website shows a different design altogether and no mention of George Washington HS. https://tioh.army.mil/Catalog/Heraldry.aspx?HeraldryId=9933&CategoryId=5580&grp=8&menu=ROTC, https://tioh.army.mil/Catalog/Heraldry.aspx?HeraldryId=9959&CategoryId=5596&grp=8&menu=ROTC. Lincoln and Sunset High Schools have the purple and white colors.

 

Wikipedia has a list of - https://en.wikipedia.org/wiki/List_of_defunct_military_academies_in_the_United_States#S. 

There aren't any of FHS listed. 

Any help would be appreciated.
