To achieve its missions, the US Army needs to take advantage of improv
ements in weapons technology. To replace the medium antiarmor Dragon w
eapon system, the army is testing a new system called Javelin. We used
simulation to explore Javelin's potential to enhance the effectivenes
s of the mechanized infantry. We developed scenarios employing the Jan
us(A) high-resolution combat model. These scenarios represent force-on
-force trials of mechanized versus fully modernized armor heavy threat
s in deliberate defense and movement-to-contact missions. Our results
indicate that the Javelin performs better than the Dragon in mechanize
d force. These findings and related study results led to the US Army's
decision to replace the Dragon with the Javelin in its mechanized inf
antry units.
