Merkava.

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?

"A single double piece vertical
rear compartment door was incorporated to allow for easy entry, exit and reloading of ammo while under fire. At times the rear area is used for armor
personnel carrier for 8 combat troops. 10 is possible and 3 man command post, 3 station med-evac with medical team is also an option among some of
the popular configurations." Lt. Amos

1982 Lebanon,
BELOW MERKAVA COMBAT TEAM MEMBER BEING DEPLOYED

These troops were carried into battle by Merks in squads of 6, 8 and even 10 men."

" Now...
there IS most surely a rear compartment area and it Does Surely exist as can be seen here.
Special Ops will deploy 7 plus squad leader while 10 combat troops were carried in 1978
during 1st public roll out and recently the Mark 4's during 2006 conflict. A Medical team is
now fielded in ten special unmarked Tankbulances that are getting the Trophy APS installed.
They have 1 doc plus 2 orderly's with 3 casualty stations. A Forward Command Post with 5
specialist depending we're talking about a company, brigade or battalion Merkava. See below.
1000's of IDF troops have ridden inside Merkava troop compartments over the past 30 years.
It's true that all the main gun 120mm ammo makes for one very cramped riding condition but,
I never saw anyone complaining of too much ammo! "

Even the model makers know about the troop compartment....

"Below model is shown with rear hatch double door closed but CAN, with some
difficulty be displayed with hatch open & interior layout complete for 8 troops"
