we've been getting KR3 range dates several times a month lately. For instance, August, we have 3 range dates, including this coming Saturday (23rd). This past weekend, we had 1 shooter use the range, most of our "regulars" were out-of-town. For September it looks like we have 3 KR3 range dates. Sometimes it's more, sometimes less, depending on the Army's usage and needs. I think Guard and Reservists also use it on weekends. We get what's left, and what we're able to staff. There's 6 shooting positions now, and if there's more than 6 people showing up, people buddy-up: e.g. one person shoots, one person spots. Something like that.
All firearms must be registered with the Army Provost Marshal Office (MP's) before bringing them on base. The PMO uses the HPD registration as their basis.
