Demolition Munition, Concrete Penetrating, HE: XM150, also
known as the Penetration Augmented Munition (PAM) is a
lightweight, portable demolition device being developed
for the Special Operations Forces. A compact 33 inches
long and weighing approximately 35 pounds, PAM can be
emplaced by a single person to defeat reinforced concrete
bridge piers, walls, and abutments. The munition can be
carried in a rucksack or strapped to load-bearing
equipment without interfering with the soldier's ability
to walk, climb, or rappel. It can be initiated by any
standard military detonation device.
The PAM is equipped with a silent stud driver and
self-contained standoff assembly for proper positioning
and attachment to the target. The silent stud driver fires
an explosive stud into the target. The PAM is then hung
against the target, using this stud and the strap
provided. The warhead consists of a forward charge, which
cuts any rebar; a hole-drilling charge, which forms a hole
in the target; and a follow-through charge, which is
propelled to the bottom of the hole where it detonates.
The explosion renders the bridge useless to mechanized
Although designed primarily for reinforced concrete
targets, PAM has applications for a wide range of
missions, especially those where tamping of the explosive
will enhance performance. PAM allows the user to place a
substantial amount of explosive deep within reinforced
concrete, earth, sand, or other targets to multiply
The current full-scale development program includes
logistics, MANPRINT manuals, and fabrication of a PAM
