Another thing. I hardly ever seem to read the blurbs of volumes that are not the first ones, especially if I don't own the thing physically. Would have definitely known it was last volume if I did.
@Alexander-Keller-Nelson Aw, I hope it could be a worthwhile investment. I'm nowhere near rich and there are plenty of already licensed manga I would prefer to buy, but I would prefer a good deal of 4-koma over a good deal of them. I've known about 4-koma's predicament for a few years now though, and this was a fun little thing, so I'm not that upset my mind got changed so easily. A $25 Amazon gift card does get me 2 of the 3 volumes released, anyway.
@Xerand This might actually be a mistranslation, because in Japanese, 戦車(sensha) can be more general than just tank and refers to basically all tracked armored combat vehicles, so arguably it should have been translated as AFV instead of tank. Don't have the raws to see specifically if they used 戦車 or not in the original though.
