It might if it had overhead cover, which became much more important in the WWII era when proximity fuzes were released to the US Army during the Battle of the Bulge, and you could add some extra dooring, but that would get in the way of a quick entry. On the other hand, we're only taking about 10-20 tons, not kilo-tons, of yield, so in pressure it's more like a Daisy Cutter or MOAB, or something smaller that hit close, and there's lots of experience of that. It might well be preferable to being overrun by a unit of the Red Army in the next few minutes, but, obviously, selecting a target at > 1,000 meters would be a good idea. My general point, though, it that this weapon is held to be axiomatically "crazy", when it's not in the context for which it was designed and fielded.
