The most context I could find was on this store selling prints: https://store.aperture.org/products/night-operations-2003-4

Night Operations, 2003–4, and Untitled, Thanh-Hoa, 1998. Night Operations is taken from Lê’s 29 Palms series, in which she documents soldiers training for active duty in Iraq and Afghanistan in a desert-like terrain in Southern California.

Still don’t explain shit.
