Although some members do have an interest in weapons, the primary thrust, with intent, is to not make them a big part of the group activities, for a variety of reasons.
One is that it we are not a militia in any shape, form, or fashion and do not want to be seen as such.
Another is that we concentrate on the preparations for natural and manmade disaster effects. And while the need for hunting, and even defense, can be a factor, the number of instances it will be needed is much less than those for which it will not be needed. (This is not to say that if needed, it is not a great need, because it is.)
A third reason is that there are those that simply do not want to deal with the subject, and we want to be able to help as many people as possible, so we keep it at a comfort level for those people that want to learn most things, just not weaponry, either because they simply do not, or because they have it covered, or because they have their own ideas on how to take care of defense.
And a fourth is there are plenty of places to get weapons information, as you pointed out.
And yet another is that we do not need the aggravation of all the various debates of what is best, and how much is needed, and how important it is, and all the misinformation that gets put out there about weapons. Those of us that have an interest pursue it, just outside of the Northern Nevada Prepper's Group setting.
Just my opinion. The official word comes from the leadership team, some of whom I believe will chime in.
