Ballistic Research Laboratories
Operations:
(BRL)
To determine blast effects on tree stands, natijral stands
on Jelete, Lukoj, and Enidrik were used as indicators of effects.
Be-
cause Of expected contamination from BRAVO and ROMEO, all pi¥oject work
was completed before BRAVO except arming of gauges.
BRL (PiHoject 1.2b)
installed self-recording, static, overpressure, and dynamic
gauges.

Participation was planned for KOON only, but the urfexpectedly
large radius of éffects from BRAVO provided additional data
