"We usually use that mostly on the weekends because we have access to the range during the week. But I can tell you a number of times they have had a training holiday at Fort Benning, so nobody trains, and to drag him in is like pulling teeth"

Nancy Johnson is referring to a training range that is readily available to utilize on the weekends. She is suggesting that it is tough to get somebody to come in and utilize the range throughout the week, even when there is a training holiday at Fort Benning. This indicates that the person she is referring to is not especially passionate about using the range throughout the week, and it takes a great deal of effort to get them to come in. This could be due to the individual being hectic with other dedications throughout the week, or merely not wishing to make the effort to come in and utilize the variety. Either way, it is clear that Nancy Johnson is suggesting that it is hard to get the person to come in and utilize the variety throughout the week.
