What is your favorite rescinded military publication?

In another thread, it was mentioned that FM 6-22 had been rescinded. (though maybe not appendix B?)

This got me to thinking, what are some of your favorite rescinded or obsolete Army publications?

Personally, I have at least 3 different obsolete/rescinded versions of the Leadership FM on my computer at home. They all take different approaches and have subtly (and not so subtly) different takes on how to approach leadership that I find valuable. The late 70's/early 80's (I'd have to look) FM 7-8 was by far the best for "figuring out what the infantry does." I have an early 60's or 70's (yellow cover) Explosives FM, which is much more .... actionable than the current version. An OLD SH or TC on rifle marksmanship that surpasses anything I've seen lately, and another shows me how to hot wire a car and other such things.

With clarity that our actions should always be in accord with current doctrine & regulations, what are some of your favorite obsolete military publications?
