(a) OBSERVATION: The angle of fall for a CHICOM 107mm rocket can be determined and can be used to estimate the range to the rocket firing position.

(b) EVALUATION: Expended 107mm rocket motor bodies peel back when they hit the ground. By setting the rocket motor body on a level surface the angle between the longltudal axis of the rocket and the surface closely approximate the angle of fall of the rocket.

2. (U) Pertinent comments follow:

a. Reference Section 2, PeraRraph 2b(l): Concur. It is noted, however, that the FADAC is equipped with an automatic power cut-off system designed to trotect the FADAC from voltage and phase variaticns.

1. (U) The quarterly report of the let Battalion, 27th Artillery adequately reflects the operation» during the reporting period.

2. (C) Reference paragraph 2d: Non-concur. Range data collected by this method has shown many inconsistencies that cannot be explained. Until such time as further data verifies the system, it should be used with reservations. The angle of fall method for determining range is probably valid only when the rocket strikes level and cleared terrain. The effect of sloping or dense jungle terrain on the peel back effect of the rocket motor body has not been determined.
