On why I think it's a ballistic missile and not an ABM:
Usually anti air missiles are hot launched due to reaction times. Larger ballistic missiles especially heavier ones are usually cold launched because the exhaust to get it up in the air is too tremendous.
I thought being cold launched ruled out ballistic missiles since I was thinking of SRBM like Iskander but realized ABM would likely be hot launched and that there are plenty of larger BMs that cold launch.
