But according to others on here, they're not allowed to improve training with more ammo, its because they're stockpiling.
My guess, after trying to implement better technology and tactics into the training curiculuum for both Navy Security and flight crew, they ran into the wall that is HQ, whether DoD or DoJ. Appointees that have zero practical experience but have connections and have never lead people into harms way. Look at the article again, the course was 50 rds, now its 60. That means a budget increase, along with ordering more ammo to allocate to training. Then it also means more range time that agents aren't in the field. It all boils down to money. They don't want to make the course longer, or cost more so they disapprove expenditures or any policy changes until someone finally has enough and pitches a big enough fit or is killed because of it.
