Fort Hood was flooded with drugs back in the 1990s. I think about half of my basic training platoon that got sent there ended up chaptered out or awol in lieu of UCMJ action after drug charges. My room mate was a NARC for the CID. He went AWOL when he realized he was still going to jail despite narcing for them. I got all his gear. gotta LOL about that.
I thought it was just the generals. Looks like more of a witch hunt.
No excuse for officers to be doing drugs, kick them out and recoup an appropriate cost for any education they got on the government dime.
