Despite upgrades and improvements, it is considered an old and vulnerable APC. To respond to the need for heavier APCs, the IDF adapted a variety of older or captured tanks to serve as heavy APCs, such as the Achzarit on a T-55 chassis and the Nagmachon and Nakpadon on Centurion tank chassis. Some heavy APCs were originally combat engineering vehicles, such as the Puma, used by the Combat Engineering Corps to transport heavy engineering materials, but due to its heavy armor, sometimes used to transport troops into hostile areas.
