![]()
- Firing against the side of the hull (at 89 degrees 28 minutes).
- Distance 200 meters. Results: 2 complete penetrations 45-50 mm in diameter. The edges of the breach were melted.
- Firing at the side of the superstructure.
- Distance: 200 meters. Result: 2 complete penetrations (#1 and #2) 45-50 mm in diameter.
- Distance: 300 meters. Result: 1 complete penetration (#3) 50-60 mm in diameter.
The angle was not calculated as the angle of the plate was not measured. - Firing at the side of the turret:
- Distance: 425 meters. Result: 2 complete penetrations (#4 and #5) 50-60 mm in diameter.
- Distance: 500 meters. Result: 140 mm deep and 60 mm wide indentation in the welding seam of the turret floor and side joint (#6).
- Firing at the rear of the hull.
- Distance: 500 meters. Result: complete penetration (#7) near the right exhaust pipe 55 mm in diameter. A second shot from the same distance resulted in a 60 mm wide indentation in the welding seam connecting the rear plate and engine deck (#8).
- Firing at the front of the hull:
- Distance: 200 meters. Result: 40 cm long groove from a ricochet, 40 mm deep indentation melted into the armour.
The shell has a tendency to ricochet due to the angle of the plate.
