Equipment that should have 100% reliability still takes attrition.
I made a Leopard (Light Tank 3) variant as Germany that had more than 100% reliability, made a division that included 4 light tanks, set up equipment so they would only take the Leopard variant and confirmed that all the divisions I would be using for the test only had the correct tank variant in stock. I set them to training. The tooltip on the attrition skull that appears when taking attrition states that the divisions have > 100% reliability and have a breakdown chance of 0%. However units still take losses.
I conducted a test wherein I fielded 7200 of this tank variant. I had 7021 light tanks in my stockpile, including about 2000 of the pertinent tank variant and set them to training for 365 days. All production was stopped. The attrition was 5.4% due to me having unlocked a land doctrine tech that reduces attrition by 10%. At the end of the 365 days I had 6273 tanks left in my stockpile, meaning I'd lost about 748, which is 2.05 daily. Using the wiki attrition formula, which I'm pretty sure is correct since I tested it with infantry, I calculated that these tanks that should have reliability >100% actually have about 94.73% reliability, perhaps 95% in the actual game code? I also conducted a short test where I had a small number of tanks driving around in the mountains on the Austrian border for a month and got a similar amount of reliability.
If there exists a cap to the amount of reliability that equipment can have, as seems to be the case from my tests, this information should be presented to the user in a clearer fashion, and in particular the attrition tooltip in question should display real reliability and breakdown chance values.
