The vehicle's only armament was a 36M 40 mm Bofors anti-aircraft gun also made in Hungary under license. The gun fired the usual anti-aircraft ammunition as well as a Hungarian anti-tank round. It had a rate of fire of 120 rounds per minute and a penetration of 46 mm at 100 m and 30 mm at 1000 m. The Nimrod carried 160 rounds.
The gun had a practical AAA altitude of 3800m(4155yd).
If Hitech allowed the 4155yd max range in AAA mode, this would make a good perk flak vehicle. And if he gave it HE and AP it would make for an interesting close quarters heart breaker when you didn't see it hiding in a clump of trees. There are very well documented gunsights and reticles for it out there so Waffle wouldn't be in a bind over that.
The real issue is the gun, 36.M was an AA version while the 40.M was the Antitank version. Kind of confusing unless Lyric can shine some light on it.
AP ammo:
The 40 mm 40.M was a standard towed anti-tank gun produced by the Hungarian company of Manfred Weisz AG (MAWAG), which was also used as a tank gun. The weapon was a derivative of the Rheinmetall-Borsig 3.7 cm PaK 35/36, but it fired the same ammunition as the 40 mm Bofors AA-Gun.
40 mm L.70 37.M Bofors/MAWAG Flak A.P.H.E. 36.M 66 mm
40 mm L.70 37.M Bofors/MAWAG Flak H.C. 42.M 206 mm
40 mm L.70 37.M Bofors/MAWAG Flak A.P. 43.M –
Main armament of 40.M Nimrod self-propelled armoured autocannon. The vehicle was an Hungarian modification of the Swedish Landsverk L-62 (LVKV 40 Anti) which had many basic parts in common with the shorter L-60 light tank. The Nimrod was taken into the Honvedseg (Hungarian Army) as a tank-destroyer, but it proved inadequate against Soviet T-34 tanks. The situation improved when new 43.M ammunition was introduced or when 42.M Kerngranate hollow-charge rounds were fired from the vehicle. Kerngranate was a 15 cm Igr. 39 Hl/A artillery shell H.C. warhead mounted on a fin-stabilized tube. The round had to be inserted into the barrel manually, from the front, and it was fired with a blank cartridge very much like a rifle grenade. A total of 135 Nimrods were built, most of which were deployed by the 51st and 52nd Armoured Autocannon Battalion of the 1st and 2nd Hungarian Armoured Division, respectively. Nimrod batteries attached to armoured and motorized battalions were allocated four vehicles each.
