Advanced Urban Combat 1 December 1999 Pdf: Fm 31 28 Fouo Special Forces

It outlines how SF teams can use drainage systems to bypass checkpoints and how to conduct sound and light discipline in the absolute darkness of a city’s underworld. It is one of the first US manuals to treat the sewer as a legitimate line of advance rather than a hazard.
