Ukrainian military buildup from 2014 represented the largest, by percentage of population, non-superpower military buildup since WWI. They weren't just building it up for funsies. What they were going to use it for, I couldn't say, but you generally don't build up that much of a military while in the middle of a civil war and not use it to retake the area that has separated.
Plus probably Crimea, since they were talking about it so much.
