This PDF is an ATP (Army Technical Publication).
ATPs are sets of procedures and training doctrines. In this case, this ATP is applicable to Brigade Combat Teams down to individual soldiers. This ATP
covers how to operate in underground facilities, what the dangers and hazards are, what to expect from typical underground facility best-practices in
terms of construction and infrastructure.
It also covers securing captured underground facilities, access control and denial procedures, classified materials handling, combat operations, and a
bunch of other topics.
It isn't just underground "facilities" as we may be imagining them. They also cover tactical tunnels (think Vietnam, Israel/Gaza tunnels, Mexican
Cartel drug tunnels etc.) and even the now little-known tactical tunnels of the Great War. One such example of tactical tunnels were dug under German
lines by British forces, packed with explosives, and detonated killing 10,000 Germans during the Battle of Messines.
While I do not doubt that the US has a network of underground bases, this ATP is not directly relating to the existence of DUMBS as described by the
