The M-18 we have already is lower faster and has a better gun. the reason i say it would see more use is not only the ENY but becuase it was quite popular with its crews during WW2.
The Jagdpanzer 38(t) was intended to be more cost-effective than the much more ambitious Jagdpanther and Jagdtiger designs of the same period. Using a proven chassis, it avoided the mechanical problems of the larger armoured vehicles.
It was better armored than the lightly armoured earlier Panzerjäger Marder and Nashorn with a sloped armour front plate of 60 mm sloped back at 60 degrees from the vertical (equivalent in protection to about 120 mm), carried a reasonably powerful gun, was mechanically reliable, small and easily concealed. wikipedia.
Its combat weight was 16 metric tons and it could travel at maximum speed of some 42km/h. Hetzer’s tracks had 96 links per side with 350mm wide tracks with track surface contact of 2.72m. Hetzer had a low well-sloped hull of welded construction. Hull had 60mm thick frontal plate, 8mm thin roof and rear armour and 20mm thin side armour. All armoured plates sloped inwards. In addition, Hetzer was fitted with small 5mm side skirts (Schuerzen). It was armed with 75mm Pak 39 L/48 gun with limited traverse (5 degrees to the left and 11 degrees to the right) and elevation (-6 degrees to +10 degrees). The gun was mounted with Sfl.Z.F.1a gun sight. Main armament was protected by 60mm cast gun mantlet - Saukopf. Heavy gun and thick frontal plate overloaded the front but it was later corrected by the use of strengthen suspension. The main gun had an effective range of over 1000 meters. For example Hetzer could knock out Soviet T-34/85 at a distance of 700m by hitting the frontal armour, while Soviet T-34/85 could knock out Hetzer at a distance of 400m by hitting the frontal armour. In comparison with a JS-2, Hetzer could be knocked out at a distance of 1000m, while Hetzer could knock JS-2 out at a distance of 100m. The limited traverse of the gun forced Hetzer to constantly change position in order to target another enemy tank, while exposing its thin 20mm side armour to enemy fire. An interesting feature was the remotely controlled MG34/42 mounted on the roof, with 360 degrees rotation for local defense.
