Re. Sherman, nope, in the inside, because the cut-off unit was behind a wide open valley drenched in MG and mortar fire. Entry and exit via escape hatch.
Same method used for CASEVAC and even for ammo resupply.
That's why did I mention it.
There was a pic of UAZ utility vehicle loaded with at least 13 soldiers. Same for a story about a British medical NCO being allowed by German tank commander only one trip to his positions to collect British wounded. Sure, in emergency (or just for the heck of it) you can squeeze people very tightly. But then I would doubt the MKerk carrying 13 wounded was combat-capable in such situation. Providing fire from its own weapons? Sure, why not, Comamnder and Loader have their hatches and machineguns, plus possibly (depending on access to it) the 60mm mortar.
Main gun? Sorry, but at best in dire emergency. If nothing elce, hot case or case stub is really NOT healthy and can potentially make more mess than any RPG hit.

Just a simple question: If Merkava is able to carry "10 fully armed and equipped soldiers" in the inside without any hindrance to its capability...
Why the heck took design of Namer so much time and why the heck was there a problem to fit even one fully kitted squad? In comparison to Merk, if Merk was able to fit 10 "without problems", then Namer should be able to carry how many. given the absence of turret? 15? 16? So there should be no problems in fitting 10 in there, right? But there are.

You just need to realise, that "emergency use" can be hardly made a rule. Sure, for example a Czech Liberator wa able to return home at night in storm over North sea with just two engines running doe 3 hours on emergency power (allowed for 15 minutes only). Does that mean all Liberators were able to run all time on WEP? A "record-breaking" IDF Centurion survived ca. 40 penetrating and non-penetrating hits from RPGs and ATGMs in 1973, does that mean all Centurions should be totally impervious to anything but tactical nuke? another Cent was able to rescue crew from another tank, does that mean it should be given a 4 troops internal carry capacity?
