Rey once overheard a pair of First Order stormtroopers discussing the new T-17 while on Starkiller Base. One of them thought that they were a "great improvement," though the other replied that "they don't hold up," and implied he knew from personal experience.
The T-17 mentions in and were added by voice actor Sam Witwer as a reference to a conversation in between two stormtroopers who are discussing the BT-16 while Obi-Wan Kenobi disables the tractor beam. Witwer also added similar lines in Rogue One: A Star Wars Story and Solo: A Star Wars Story, which mention the T-15, and in which mentions the T-18. Similar reference to the T-16 was added in "Part III" of the series Obi-Wan Kenobi. The mention depended on the era.
