The turret makes me think it's an AMX40. Guess the only person who knows is the artist~
Edit: Nvm the artist's comment says something something TOG: TOG抱き枕欲しい。tier9の洗礼を受け封印したコメットさんを引っぱりだしてみた。速攻でT54小隊、E75の洗礼を受けて泣きそうになった。
Google Translate rather hilariously renders this:
the babelfish said:
TOG pillow want. the baptism of tier9 received I tried to pull out a sealed the comet's. Haste in T54 platoon, I was almost crying after receiving the baptism of E75.
I'm not sure if "baptism" means that he unlocked the E-75 (a Tier IX tank), or if it's a sarcastic reference to having been killed by one in his Tier VII Comet. No idea where the T54 platoon comes into it.
Whatever the details, it's pretty clear that that is in fact a TOG pillow. :)
