APC/IFV armor in details

Recommended Posts

Some pics of the Marder 1A3's spaced armor:

















Tested against 30 mm AP from 400 m distance; no penetration




UFP after shot by 35 mm PELE (at least that was claimed on a German forum once); no penetration of the base armor


(lower vehicle is BMP)

By the way, given the armor of modern IFV´s are guns like 35mm oerlikon capable of engaging them from the front or are they limited to side engagements? Same for engaging tanks, are Autocannons usefull for  engaging tanks from the side?


It depends on the ammunition and range, but in general yes. Even an old 35 mm APFSDS round from the late 1980s/early 1990s can penetrate 100 mm steel armor at 2,000 m distance. A more modern design with longer penetrator should be able to deal with quite a bit more armor.


Modern IFVs are often designed with very limited amounts of additional protection over the demanded/desired protection level due to the large physical size and the relatively low weight spend on armor. The CV90 Mk II and CV90 Mk III for example are both designed to resist 30 mm APFSDS ammo (from 1,000 m distance), but they are not meeting the NATO STANAG 4569 level 6 standard (protection against modern 30 mm AP, APDS and APFSDS ammunition from 500 m distance along the frontal arc). The difference in armor penetration of a 30 mm APFSDS between 500 m and 1,000 m is probably just about 5-10 mm steel.


So a 35 mm gun, a 40 mm or a 57 mm gun would probably cause quite a lot of trouble for some of the lighter IFV types that are designed to just reach protection against 25 mm/30 mm rounds.

Sorry but polish manufacurer this armour is fucken angry about those photo in net.


Sounds like a good reason to post the photos again :anticipation:. Doesn't bother to paint the armor on the inside, but then gets angry when someone takes a photo...

      hello everyone!
      so i read that the T-90 shares the T-72B turret , thus BDD armor , however this documentary (?) : https://www.youtube.com/watch?v=lKGv5JQBTI8 says "aluminums and plastics".
      is this any legit? did they like , keep the t72b cavity design and change the fill?
      also , did the combination on new welded towers change?

      Most historical arms and armor were made of metal, leather and stone.  This is the thread for historical weapons and armor made of weird shit.

      This is an example of armor made from the Gilbert islands made of thick, woven coconut fiber.  The helmet is made from a pufferfish.
      I've seen a set similar to this in another museum.  The woven fiber body armor looked like it would be reasonably effective.  Coconut husk is pretty tough and the vest was very thick.  I wasn't so sure about the helmet.
      The Gilbertese were also the foremost users of shark's tooth weapons, although other Polynesians used them as well:

      Several historical examples I've seen are these strange, branching designs:


      Polynesians were not the only ones to use teeth in their arms.  The Mycenian Greeks made helmets out of boars teeth.  One such helmet is described in the Iliad, and there are a few archeological discoveries of such:


      And finally, a club used by Inuits made from the penis-bone of a walrus:

      This is wonderful.
      I learned:
      1)  The leo 1 had poor hull armor, but excellent turret armor!
      2)  Chieftain's armor was 16 inches thick!
      4)  The T-64 was the Soviet's own version of the leopard(?!)
      Actually, the materials science stuff seems solid, and jives with what I've heard before (but how much of that is people repeating this article?).

      "Special armor?"

      It's all fucking NERA.
      Some models of T-72 had it.
      Merk IV's have it.
      Abramses have it.
