You should read a book called "The battle of Fallujah" cited in the paper

What would be the point in using something like that at Fallujah?  To
the best of my knowledge, the fighting was mostly in residential areas,
of houses made of ordinary building materials (mostly concrete block,
from what I could see.  There would be no reason to use some
super-secret advanced bunker-busting weapon.  Even conventional armor
piercing projectiles would be of less value in that kind of environment,
as they would pass right through the target building, leaving relatively
neat holes front and back, with matching holes in non-targets down
range.  Much more desirable from the military's point of view would be
weapons that would enter the target and blow up, killing the people in
the target without doing damage to nearby structures, where your people
might be.  Given that the military has many such weapons, and that they
are undoubtedly cheaper that the hypothetical super-secret weapons, it
seems unlikely the military would go with the more expensive, less
effective option, just to give activists something to catch them at.

         This is more of Busby's lunacy.  (See his message way below.)

         Under the heading "The Battle for Fallujah" Busby's paper says:

"CAS (Close Air Support) weapons included AGM-114 Hellfire, AGM-65 
Maverick and TOW missiles. These mainly use shaped charge warheads 
believed to contain Uranium shaped charge liners (concept identified 
in US Patent 4441428 [fn 55]).  CAS operations in Fallujah also used 
500lb GBU-12, 38 and possibly larger hard target guided bombs e.g. 
GBU-24 for hard targets and suspected bunkers. The advanced 
penetrator warhead versions of these (BLU-110, 111) use high-density 
metal ballast - either tungsten or Uranium [fn 57]."  (The footnote 
numbers are the ones in Busby's paper.)

         For patent 4441428 (fn. 55) go to this link

http://www.patents.com/us-4441428.html

         The abstract to the patent reads, "This invention relates to 
a new Blasting Device especially adapted to drilling oil and gas 
wells, characterized by a shaped charge of explosives, having a liner 
of depleted uranium."

         According to Busby's lurid fantasy, this "concept" (his 
word) of a blasting device to be used for drilling oil and gas wells 
was being used as a weapon in Fallujah.  You may make of that what you
will.

         The device in Busby's footnote 57 is described by this
abstract:

"A target penetrating aerial bomb including a penetrating body shaped 
for improved target penetration, having a narrower impact profile at 
approximately the same weight as an existing bomb. An aerodynamic 
shroud encases the penetrating body and emulates the aerodynamic 
shape of the existing bomb, and the weight, center of gravity, and 
moments of inertia of the bomb closely approximate those properties 
of the existing bomb. The bomb constructed according to the present 
invention may be qualified by similarity to the existing bomb, thus 
avoiding lengthy and costly qualification procedures."

         This bomb is a bunker buster bomb intended for use against 
hard targets, and is not a penetrator (anti-tank) weapon for use 
against armored vehicles, as Busby correctly says below.  Hence, 
**technically,** --- and only technically --- Mike Brennan was 
incorrect when he mentioned its use against armored vehicles.  Note 
however that Mike said "presumably mostly against armored 
vehicles."  **presumably**  Not being an expert on this weapon he 
didn't know its application.

         A Google search for patent 6639977 (in Busby's fn. 57) will 
take you to this Wikipedia link:

http://en.wikipedia.org/wiki/BLU-116

         According to the Wikipedia article, some organizations have 
linked the BLU-116 bomb to depleted uranium.  However, the article 
continues, these claims "do not constitute evidence that either 
material [tungsten or DU] was used in the actual weapon."  The patent 
application describes this device as a "shrouded aerial bomb," and 
says it can use DU.  That doesn't prove anything about its actual use 
in Kosovo, or anywhere else.

         The patent link is

http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL
&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=6,389,977.PN.&OS=
PN/6,389,977&RS=PN/6,389,977

         The patent description says DU can be used in the 
bomb.  Whether or not is has been used, and on what battlefields (if 
any), is another matter entirely.

         Of course Busby's huffy correction (just below) is 
irrelevant and immaterial.  The dispute is over the human health 
effects of DU, and not whether or not a weapon is an anti-tank 
penetrator.  As he often does, Busby pitches a fit over a minor or 
insignificant error while cleverly ignoring the larger or fundamental 
part of the debate.  For instance, on Oct. 15, he corrected someone 
by saying that he was a Visiting Professor, and not an Visiting 
Assistant Professor.  He harangued us for over a week to read his 
Fallujah hair sample paper.  After I posted a critique of his paper 
he managed to maintain a thunderous silence.
