Pz. Kpfw. III Ausf. E
Taking the 5th spot for shortest lifespan is the German Tier 3 Light tank, the Pz. Kpfw. III Ausf. E. This fast little tank has an average life duration of a mere 2 minutes 51 seconds, which is barely enough time to affect the flow of a battle.
With a wide selection of guns, the Panzer III E can slot into a variety of play styles, but the 5 cm Kw.K has 60 mm of penetration, allowing it to punch through some decently thick armor for its tier level. Just be careful of the engine, as it is one of the many tanks who's engine catches fire easily. Always pack an extinguisher!
