What's the "OD Note" business? Officer of the Day? If so, why is s/he reading the mail of a light colonel? And why injecting their own notes?

From actual, bona fide letters I've seen they're not censoring the mail any more than was done in Vietnam or Gulf I, i.e., not at all.

*IF* this letter is genuine, and I have my doubts, the LTC's buddies have done him one helluva disservice. The last thing the military needs is to have this kind of thing all over the Internet, and LTC's career will take a nosedive if the powers that be find out who was stupid enough to write it.

I did some checking: the abbreviation used by the US Army for Special Operations is NOT "Sp Op Com" but "SOC" -- Special Operations Command. The first sound like the Navy: BuPers, BuShips, etc. Either the LTC is making up his or her own abbreviations, the guy's in the Navy, or whoever wrote it doesn't know the military.
