Jagdpanzer E 100 - 3 Marks of Excellence

This was my very first 3 marks challenge in Tier 10. I gave up this challenge more than 8 times and lost more than 10 million credits. I can't recall how many times I had sold my Jagdpanzer E 100, but I bought it back after the "Arms Race" clan wars event to retry the challenge. The Jagdpanzer E 100 has the choice of loading a devastating HEAT shell with 420mm of armour penetration, pulverising many heavily armoured vehicles at close to medium range. However, both HEAT and AP shells tend to hit the enemy vehicle's track with 0 damage output. This is because it has an extreme caliber of 170mm, having a higher chance of shells being absorbed by the enemy's tracks. Although the Jagdpanzer E 100 is extremely sluggish and slow in performance, it boasts great armour to deflect shells from some tier 10 TDs and HTs. Having great armour comes with 4 obvious weakspots: cupola, side cheeks, lower plate and the track itself. The engine tends to break when the lower hull is shot, the gunner tends to die when the side cheeks are shot and the commander tends to die when the cupola is shot. The cupola acts as a vision port, meaning that the Jagdpanzer E 100 can spot enemies even when the whole tank is hiding behind terrain or rocks. The Jagdpanzer E 100 has great view range that can be achieved without needing coated optics, so it would be a good idea to swap out coated optics for vents. Although the Jagdpanzer E 100 deals around 1050 damage per shot, it will be extremely vulnerable during the 20 second reload. Never go alone, always have an ally beside to defend the sides and rear of the Jagdpanzer E 100. This is the hardest 3 mark challenge yet, it made me very angry and disappointed in many battles.
