Help with helmet liner unit mark

[FestungSpanien]

Hello,

I am looking forward to seeing if someone can identify this Korean war period US helmet liner unit mark.
There's another unit mark to the other side of the liner but overpainted.
Markings on the liner are CAPAC 52 53.
Many thanks for any help provided.
Regards,
Ace

Ace,
The unit emblem is for the 560th Engineer Bn., Authorized Aug. 15, 1957. The unit did see service in WW2- Normandy, N.France, Rhineland, Ardennes, Alsace, and Central Europe. No other combat service noted (Book was printed in 1993.)

No idear on the other emblem....too bad they painted so many of these over and over again...
