I've learned most of what you posted from FM20-3:
CAMOUFLAGE, CONCEALMENT, AND DECOYS
http://www.globalsecurity.org/milita...m/20-3/toc.htm

There is also the first chapter of FM21-75:
COMBAT SKILLS OF THE SOLDIER
http://www.globalsecurity.org/milita...-75/index.html

And section 1 of Chapter 4 in FM23-10:
SNIPER TRAINING
http://www.globalsecurity.org/milita...-10/index.html

Appendix D of FM5-103 discusses camouflage of various position types:
SURVIVABILITY
http://www.globalsecurity.org/milita...103/index.html

There is a small section on Mountain camouflaging in chapter 2, section 4 of FM3-97.6:
MOUNTAIN OPERATIONS
http://www.globalsecurity.org/milita...7-6/index.html

And lastly, here's FM27-76-1, which has alot of emphasis on Concealment and Cover:
SURVIVAL, EVASION, AND RECOVERY
http://www.globalsecurity.org/milita...6-1/index.html

Here are a couple manuals on Urban Operations, which discuss movement best practices:

FM90-10-1
AN INFANTRYMAN'S GUIDE TO COMBAT IN BUILT-UP AREAS

FM3-06.11 (Chapter 3)

http://www.globalsecurity.org/milita...my/fm/3-06-11/

If you are ever looking for other FMs for other purposes, this site has a decent library:
