how much do you want to bet this language includes the land surrounding the building?
as a federal employee - i know that it is illegal for me to carry a gun in my car on the grounds (i.e., parking lot) of the fed building where i work - as long as that parking lot is on the grounds of that building
this is the part of the statute that you says allows guns on a federal facility:
my thoughts are that your interpretation is "lacking"
as for the military commander - they have the right to set rules for the installation - and while a general article of the UCMJ would be used (Failure to Follow Order or Regulation) to cover that - I can't think off the top of my head how a civilian would be charged
however, i can tell you this - i was the Special Agent in Charge of the Fort Sam CID office from 99 to 04 - and I'm confident based on experience that if you take a firearm on to an installation outside the posted rules, - you'll be cited and asked to appear in the magistrate court. your weapon will be confiscated (not theft) and released to you as you exit the installation.
again - feel free to conduct your own legal analysis and form your own opinion
The term “Federal facility” means a building or part thereof owned or leased by the Federal Government, where Federal employees are regularly present for the purpose of performing their official duties.

this is the part of the statute that you says allows guns on a federal facility:
(d) Subsection (a) shall not apply to— (1) the lawful performance of official duties by an officer, agent, or employee of the United States, a State, or a political subdivision thereof, who is authorized by law to engage in or supervise the prevention, detection, investigation, or prosecution of any violation of law;
