RANGE ESTIMATION/ RANGE CARDS OTOA BASIC SNIPER COURSE The mission of the Ohio Tactical Officers Association is to enhance the performance and professional status of law enforcement and first responder personnel by providing a credible and proven training resource as well as a forum for the development of tactics and information exchange.
LEARNING OBJECTIVES IDENTIFY METHODS FOR OBTAINING RANGES IDENTIFY FACTORS THAT AFFECT RANGE ESTIMATION WITH A SCOPE, PROPERLY READ THE MIL SCALE COMPUTE RANGE TO TARGET UTILIZING THE MIL RELATION FORMULA CONVERT METERS TO YARDS DRAW A PREPARED RANGE CARD DRAW A FIELD EXPEDIENT RANGE CARD The mission of the Ohio Tactical Officers Association is to enhance the performance and professional status of law enforcement and first responder personnel by providing a credible and proven training resource as well as a forum for the development of tactics and information exchange.
TYPES OF SCOPES FIXED POWER: NO ADJUSTMENT NEEDED VARIABLE POWER FIRST FOCAL PLANE: THE RETICLE WILL CHANGE IN SIZE WITH THE DIFFERENT POWER SETTINGS AND MILS CAN BE READ PROPERLY VARIABLE POWER SECOND FOCAL PLANE: THE RETICLE WILL NOT CHANGE AS YOU ADJUST THE MAGNIFICATION SETTING. CHECK FACTORY RECOMMENDATIONS. SOME SCOPES WILL NEED TO BE AT THE HIGHEST MAGNIFICATION OTHERS MAY BE SET AT 10X The mission of the Ohio Tactical Officers Association is to enhance the performance and professional status of law enforcement and first responder personnel by providing a credible and proven training resource as well as a forum for the development of tactics and information exchange.
