An Army drill sergeant has been charged with sexually assaulting 12 female soldiers and threatening to have some kicked out of the Army if they didn't comply, NBC News reported. A two-day pre-trial hearing was held this week to determine if Staff Sgt. Angel Sanchez, who has been transferred to a desk job, will be court-martialed for the alleged assaults, a base spokeswoman said. Sanchez's lawyer said he has "serious concerns about the credibility of the witnesses making these accusations," according to the Associated Press.
