This is a Japanese ad for the online game World Of Tanks. The ad isn't age-restricted on Youtube but when I asked one of the mods, he wanted me to tag it as NSFW anyway

It's here because if it wasn't obvious, the class in which an Asian girl sculpting a white model and the painting ending up being a 'big cannon' it's a clear case of "muh fetishization", "muh white worship", you know, the usual. I'll post some examples of the other way around happening when I get the chance, but this one is the funniest in my opinion.

I tried posting it as a gif that I got from here but it wouldn't let me because the file was too big and the gif too long even when I resized it

I'm pretty sure it's just a joke about tanks (read: the subject of the ad) being more interesting than [whatever isn't subject of the ad], like every other bait and switch ad of this variety
