I was at Takhli from Apr 65 to Apr 66 with a short 3 month TDY to NKP. I was Security Police and I know that vegatation control spraying was being done at ammo storage areas and perimeters/ We had tried having live goats in the ammo storage to control tall grass and weeds, but a lion ate the goats, so chemicals were used. The Civil Eng folks applied the chemicals I believe.
