WMG / Command & Conquer: Red Alert Series

The word "Tank" has a broader meaning in the Red Alert timeline(s)

It is noted in the Tanks, but No Tanks page that there are some vehicles in the games called "tanks" that aren't actually tanks... but this is by OTL definitions, who weren't really fully nailed down until late World War II, while Red Alert diverged in 1924. It is entirely possible that "tank" in the Red Alert timeline came to mean something like "fully track-using armored fighting vehicle not meant to carry infantry".
