Re: Low-Tech Forces in DSII

A few notes about Kevlar, etc.

Blunt trauma.  I have heard rumors about people being killed by it for
years, but have not found confirmation.  However, serrious internal
injuries have been documented.	Still it is much better then being
penetrated...

Teflon coated bullets.	The teflon is there to protect the rifling of
the barrel the bullet comes out of, not to penetrate kevlar.  This is
because the bullet is composed soley of very dense and tough metal,
typically tungston carbide.  If the barrel is not protected, after a few
rounds, the gun firing it would be a smoothbore.  This means both
stabilization and accuracy would be severly affected.  A jacket on AP
rounds is not ideal.  The jacket deforms on impact.  This absorbs energy
that would be better used penetrating the target.  Teflon coated bullets
penetrate more kevlar then traditional bullets because of the following
reasons.  1.  Higher velocity, these rounds are typically loaded to +P
or +P+ levels.	2.  No energy absorption due to bullet deformation when
it impacts; the smaller area impacted, the less energy required to
penetrate.  3.	Bullet design; the tip of these bullets are considerably
smaller then the base, this allows them to focus all of the energy at
that smaller diameter when they impact a target.  

The Soviet 5.45 mm pistol round.  This round has been maligned for years
by western defense experts.  It is a small bottle neck round about equal
in power to a .22 Long Rifle.  A couple of years ago the Britts finally
tested it (or the data of previous tests was released) and that little
round will penetrate more kevlar then a 9mm teflon coated AP bullet. 
They also found out that it was much more lethal then they thought, the
projectile tumbles after impact...
