Rule 1
Direction is sent to the nearest ( ). Determining direction when measuring from a KP use (LARS or RALS?).
10mils
RALS
Rule 2
Range is expressed to the nearest ( ) meters.
100 m
Rule 3
The minimum vertical shift is ( )m and expressed as (. ) or (. ); measured in (. )m intervals.
35
Up or down
5
Lateral shift is determined by multiplying the (. ) to the KP to the nearest (. )m by the angular mil deviation from the KP to the target, rounded to the nearest (. )m
