That seems like a weird target.

It doesn't look to me like it was a refrigerated warehouse, either from the bottled drinks or the thin roof.

I doubt that Ukraine was using it as some sort of secret transit point for military goods -- according to the article, Russia had hit the chain's warehouses before, last year, so it'd hardly be secret. And security at the warehouse probably wouldn't be fantastic.

The grocery store goods in the warehouse probably have some commercial value, but not an enormous amount.

The warehouse itself doesn't seem like an incredibly critical target (which is one reason I was looking to see if it was for refrigerated goods, because I could believe that there might not be many of those). Like the grocery chain can probably just use another warehouse, even multiple smaller ones, if they have to.

It probably disrupts everyday life somewhat more than most targets, but it doesn't seem like it's on the level of being critical the way electrical power is.

I've seen video before of Russia hitting stores, including one last month. So I guess it really is possible that they'd just like to disrupt good distribution, but that seems unlikely to be something that one can really shut down effectively.
