- The US military (including the Army) showed early interest in Starlink's potential, but this was exploratory rather than as the inaugural customer.

- As early as 2018–2019, SpaceX received funding and contracts (e.g., a $28.7 million award) to study and test military applications of Starlink technology, focusing on things like aircraft connectivity.

- In October 2019, SpaceX's President Gwynne Shotwell publicly mentioned the US Army as a potential future customer for Starlink.

- In May 2020, the US Army signed an R&D/testing agreement with SpaceX to evaluate Starlink's performance for military field use over three years. This was a trial to assess feasibility (e.g., low latency, bandwidth in remote areas), not a full commercial subscription or "first customer" status. Actual field testing and pilot programs by the Army ramped up later (e.g., 2022 in Europe).

- Starshield is SpaceX's dedicated business unit and satellite network designed specifically for government and national security applications, building directly on the technology and infrastructure of the commercial Starlink constellation.

- While Starlink focuses on providing broadband internet to consumers, businesses, and general users worldwide, Starshield adapts and enhances that foundation for more secure, classified, and military-oriented needs. It was publicly unveiled in December 2022, though related work (including contracts) began earlier.

I was probably conflating the exploratory articles with their intent to go that direction.
