1. BACK UND. The Comb t Vehicle Survivability A Cell
(CVSAC) conducted a study to identify the potential survivability
impact of installing an on an armored vehicle. The CVSAC used
Cundwars, a force-on-force stochastic computer model developed
an aintained by AMSAA, to analyze the benefits accruing from an
' [idea LWR capable of providing precise direction to a threat
laser source. AMSAA has reviewed and concurred with CVSAC's
methodology and analysis results.
2. ASSUMPTIONS/SET-UP. This analysis considered a one-on-one
scenario in which Red and Blue tanks attacked and defended.
During the attack, the tank (Red or Blue) was fully exposed;
during the defense, the tank was in hull-defilade. There were
2000 repetitions of this scenario made during this analysis.
During each model run, Red was assumed to have already acquired
Blue. The effectiveness of the Blue tank when equipped with an
LWR was compared to a basecase in which no LWR was present. >
3. RESUL Laser Warning Receivers provide early warning of
impending threat engagements.KAn LWR capable of locating a
threat laser source to the degre needed to cue a main gun
engagement benefits the Blue tank ring both the attack and the
defense. The LWR's greatest impact o Blue tank survivability is
at ranges greater than 2500 meters. Th LWR's impact on Blue
survivability is not as great at ranges i hich Red tanks have a
high probability of achieving first round kilUs against Blue
tanks. At close range, the LWR competes with ot r tank target
acquisition systems.
4. THE WAY AHEAD. This analysis suggests that an LWR's bility
to locate threat laser sources and cue tank main gun engagehents
will provide a significant improvement to a tank's survivabilft.
and lethality. Follow-on analyses will: '-
a. Examine the sensitivity of the LWR's benefits as a
function of direction of arrival accuracy; and
b. Assess the impact of linking the LWR with other
countermeasures.
