Going a bit of track here topic wise but I suppose brain-storming is also a “creative” endeavor.
Since I took part in the “how tough can zombies be” talk I had a few new ideas to that subject.
A more powerful zombie(s) could actually take apart any man made vehicle or structure including MBTs.
How about a Super Soldier experiment gone real bad resulting in an extreme strong and resistant “new life/dead” form similar to how Biohazard/ Resident-Evil works.
The “real bad” part being of course a more then negative effect on the mental state of the subject causing them to hunt and kill/turn other humans instinctively like a fearless carnivorous animal.
A human turned/infected with an infused mutation virus could easily become 10 times as strong allowing for incredible strength feats like tearing open most doors within a second, breaking through walls and even concrete given time and numbers.
Therefore it could be possible for them to simply force open any kind of tank hatch since they are not built to withstand a lot of pulling force.
