(i) With the firing section as the center, draw the arc of a circle with a radius equal to the sum of the maximum intercept range and the Distance X from table 12–1 as determined by intercept altitude to intersect the lines defining the trajectory corridor, the primary danger area, and the lateral secondary danger area. This arc defines the maximum range boundary of the primary danger area. (j) With the firing section as the center, draw the arc of a circle with a radius equal to Distance X, plus 7,500 m (the width of Area B) intersecting the lines defining the outer boundaries of the lateral secondary danger area. This arc defines the boundary of the maximum secondary danger area (Area B). (k) If the intercept range is less than 16 km, the inner boundary of Area A is the Distance W from the intercept point and the width of Area A is 4,200 m at that range. All other procedures listed above apply. 12–8. Trajectory corridor Trajectory corridors are constructed by scribing concentric semicircles indicating the position of missiles for various times of trajectory (see fig 12–7). By computing range-to-impact on ballistic trajectories for destruct times correspond- ing to time intervals for selected range positions, it is possible to establish destruction points which will ensure that missiles impact within respective impact areas. By calculating an angle of trajectory that is required to place a missile on the limits of a known impact area for each side of the line of firing, points may be fixed on the range time semicircles, both to the left and right of the line of fire, indicating the position at which the missile must be destroyed if impact is to be within the impact area. By connecting these points with a solid line, the trajectory corridor may be established for the training complex or range. Missiles will not be permitted to go beyond the limits of the trajectory corridor.

Chemical agents The use of lethal or incapacitating chemical agents in training is not authorized. Chemical agent use must be addressed case-by-case in special safety analyses. The exception is the Chemical Decontamination Training Facility, Fort Leonard Wood, MO, where training regularly involves live chemical agents. 13–2. Riot control agents a. Except when prohibited by regulations or higher authority, commanders may use riot control agents (RCAs) in training, subject to the following: (1) Use of RCAs in training is limited to 0–CS. All other RCAs are prohibited for training use. (2) Use of RCAs in training requires supervision by personnel specially trained in field behavior, individual protection, and first aid for RCAs. Army personnel that meet these criteria are chemical officers (branch code 74), chemical NCOs (MOS 54B), school-trained chemical, biological, radiological, and nuclear (CBRN) officers (SSI 3R) and NCOs (SQI C). Marine Corps personnel that meet these requirements are MOS 5702 CBRN systems defense officer, and MOS 5711, CBRN defense specialist. (3) RCAs will not be used under conditions that are dangerous to life or property. Minimum safe distances to heavily traveled installation roads, railroad right of ways, airfields (including all aircraft landing areas), or inhabited areas are: (a) CS chambers will be at least 100 m away from heavily traveled roads, 500 m from aircraft operations and inhabited areas, and 1,000 m from the nearest installation boundary unless the CS chambers are designed to contain and filter all CS gas. 166 DA PAM 385–63 • 16 April 2014
