SUBJECT: Groundwars Analysis of the Laser Warning Receiver(LWR) - Phase II.
1. PM Survivability Systems and the Tank Automotive Command
(TACOM) have formed the Combat Vehicle Survivability AssessmentCell (CVSAC), a computer modeling cell to perform in-houseanalyses of survivability technologies.
2. Enclosed is the report of Phase II of the Laser WarningReceiver Groundwars analysis. This is the second of four phasesof an ongoing study. In Phase I, the CVSAC showed the benefitsof an LWR capable of locating a threat laser source to the degreeneeded to cue a main gun engagement. Phase II examined an LWRlinked with the tactics of popping smoke, seekina cover inattack, and moving to an alternate fire position in defense.
3. For further information, please contact Mr. Dennis Bjorakeror Ms. Lisa Jokubaitis, DSN 786-7759. DTIC

LASER WARNING RECEIVER (LWR)EFFECTIVENFSS ANALYSIS (PHASE II)
EXECUTIVE SUMMARY
1. BACKGROUND. The Combat Vehinle Survivability Assessment Cell(CVSAC) is conducting an on-going study to identify the potentialsurvivability impact of installing an IWR on an armored vehicle.The CVSAC used Groundwars, a force-on-force stochastic computermodel developed and maintained by AMSAA. In Phase I, the CVSACshowed the benefits in a one-on-one scenario of an LWR capable oflocating a threat laser source to the degree needed to cue a maingun engagement. In this phase, Phase II, the CVSAC analyzed thebenefits of an LWR linked w.ith the tactics of popping smoke (inattack and defense), seeking cover (in attack), and moving to analternate fire position (in defense) upon activation of the LWR.AMSAA has reviewed and concurred with CVSAC's methodology andanalysis results.
2. ASSUMPTIONS/SET-UP. This analysis considered an m-on-nscenario in which Red and Blue tanks attacked and defended.During the attack, the tanks (Red or Blue) were fully exposed;during the defense, the tanks were in hull-defilade. There were2000 repetitions of each scenario made for this analysis. Theeffectiveness of the Blue tank when equipped with an LWR wascompared to a basecase in which Blue had no LWR, did not popsmoke, did not seek cover, and did not move to an alternate fireposition.
3. RESULTS. Laser Warning Receivers provide early warning ofimpending threat engagements. An LWR capable of warning the tankcommander to pop smoke or take evasive maneuvers benefits theBlue tank during both the attack and the defense. The LWR's had agreater impact on Blue tank survivability in the defense than inthe attack. The LWR linked with popping smoke showed morebenefit than when linked with seeking cover or moving to analternate fire position. This analysis suggests that an LWR'sability to warn of an impending engagement and take measures tobreak line-of-sight will provide a significant improvement to atank's survivability.
4. THE WAY AHEAD. Follow-on analyses will:
a. In an m-on-n scenario, examine the effectiveness of anLWR capable of locating a threat laser source to the degreeneeded to cue a main gun engagement. The analysis will examinethe tactics of returning fire, popping smoke, seeking cover, andmoving to an alternate fire position.
b. Examine the sensitivity of the LWR's benefits as afunction of direction of arrival accuracy.
