what is the name of this tank?(walking daed s04e07)

TheKroo: Now the reasons why they have used this vehicle could be many, both practical for the set crew (it is easier to borrow a M60 Patton for filming than an Ambrams) or they simply wanted to paint a certain image - in case of emergency, you take what you can get. In this case that being an older variant of AFV, but still a working one, and better than none.
