Yes, it does....as a general point, EVERY RETIREE IS ENTITLED TO A CEREMONY.
Here are the Army/ARNG specific references:
"8–10. Retirement ceremony Army National Guard leadership will ensure all Soldiers have an opportunity to participate in an appropriate retirement ceremony and receive the standard Army Retiring Soldier Commendation Proram Package as outlined in paragraph 2–2. The Commander, IMCOM (para 1–4i) is not responsible for funding the Army Retiring Soldier Commendation Program package to honor Soldiers retiring from the ARNG. All ARNG retirement applications need to indicate whether the retiree has received the commendation package, by attaching a generic memorandum indicating receipt of the package." AR 600-8-7.
"2–2. Principles of support The military personnel system will include a function to— a. Provide Soldiers, regardless of component, the opportunity to participate in an appropriate retirement ceremony as determined by the commander. b. Honor individual retiring Soldiers and their Families in recognition of careers of selfless service to the Army and nation, by issuing the standard Army Retiring Soldier Commendation Program Package upon retirement.
(1) The Army Retiring Soldier Commendation Program Package includes the following:
(a) Fully personalized, full-color letter signed by the Secretary of Army, Chief of Staff of the Army and Sergeant Major of the Army.
(b) Full-color box carrier.

Note that I am not calling out or criticizing (at least not specifically)
@FloridaInjuredInCombat for asking the question. (I am glad he did, because it offers a chance to re-emphasize a point).
BUT- Since the inception of this site and DESPITE my posting on this issue dozens (or maybe hundreds) of times, folks get this wrong and need to understand....a retirement is a retirement. It is not an "Active Duty" retirement, and it is especially neither a "Active duty Disability Retirement" or a "Reserve Disability Retirement." Folks habitually want to lessen or increase the impact or importance of their component, status, or other distinction when analyzing or understanding the compensation or benefits (including retirement ceremonies) upon retirement. RETIRED=RETIRED. (I know I will be restating this again and again as people seem to not want to believe me; to an extent, this is understandable because so often, like the OP faced, some random Senior NCO or Officer will state something to the contrary....I can't account for stupid or willful ignorance of law and regulations).
(The law you are retired under will drive your compensation and how it is computed....years of service times 2.5%, disability rating multiplied by 2.5.% times years of service, or points for reservists retired for length of service).
Folks, please accept this as a baseline truth- RETIRED=RETIRED. There can be permutations and different outcomes for the retiree; but, as a 97% solution, what I wrote is the case.
Now, go get all you are due!!!
