Do we have an emotional bias that makes us reluctant to part with obsolete or outdated weapons and equipment? If so how do we move past this?

Iron sites, land navigation using compass map and protractor, field telephones that require wire to laid - all these things will work in the event of an emp - plan for every contingency - and all surprises will be mitigated.

I think the saying is, "If it ain't broke don't fix it." Just because something is old doesn't mean it's inferior.

When I turned 18 I bought a Mosin Nagant 7.62x54 rifle. It took me a while, but I finally learned how to use the damned elevator sight. It was an accurate, powerful, and sturdy firearm. A friend of mine had a Willys he got at a military auction still in the original shipping crate. Put it together, and it went practically everywhere.

As the soldiers and Marines below have said in various ways - hope for the best, prepare for the worst. There's nothing wrong with learning both. I can use a map even though my phone has a GPS feature.

Some of the old weapons are superior to the newer ones, especially in accuracy, JS.
