Sample 1:
The Flame Resistant Assault Suit coveralls were part of the US Marines’ Close Quarters Battle Equipment (CQBE), intended for ship-boarding actions. The CQBE also included an armor vest with pouches that are attached via an ABA-style velcro and snaps system. The Assault Coveralls do not appear to have been widely issued or made, so the standard flight suit was authorized as a substitution [1]. An example of the armor vest and pouches can be seen here: https://www.gear-illustration.com/2020/09/21/marine-close-quarters-battle-equipment-assault-vest-system-cqbe-avs/.
The design of these coveralls is very similar to the vehicle crewman’s coveralls. The coveralls on this page were found together with a Navy SEAL modified Desert MARPAT top.

Sample 2:
Identical to the coveralls above except for the tag and green Velcro loop on the chest. These coveralls were likely issued to a Force Recon Marine who joined MARSOC since they were found with this combat shirt made by modifying a BDU [2]:
Usage Photos:
The similar CWU-27/P flight suits are far more commonly used (likely due to much higher production numbers), but the Flame Resistant Assault Coveralls can be identified by the arm pockets that are on both arms. CWU-27/P flight suits do not have a pocket on the right arm (as worn).
