@AndreiBtvt Leitz rangefinder patent DE2156617A1 & DE2460805C2: image-correlation optics use a grating as a spatial-frequency filter. Two rhomboid prisms create a 350 mm effective baseline giving ±15 m accuracy. This principle apply to EMES 13 series for Leopard 2 prototype.
@HiKikisundal China may not only match a single european country. Northeastern China shares many similarity with Deutchland. Also notice that France is the biggest agricultural state of West Europe. There's also memes about how Shannxi Province similar to Britain
@Chieftain_armor For Wiesel's transmission:
A ZF 3HP22 gearbox and ZF LGG 110 steering gear coupled together. LGG 110 is a Cletrac type steering system with D/L selection to expand gear ratio.
Steering control via steering wheel, actuating hydraulic brakes.
Very similar to 1930 Leichttraktor.
@Chieftain_armor (3/3)Wiesels were tested in 77-78 and prepared for production, but suddenly end-up in 78.
Because NATO decided to establish E-3A EWACS fleet, Bw cancelled Wiesel project to save budget, while asking Porsche to refine the design.
1986 new prototypes evolved into today's Wiesel.
@Chieftain_armor (2/3)The design requirements was announced in 73/7/5 for an armoured weapon carrier, carrying ATGM/20 MK/120 Mrs. And in 74/4/18 Bw chose Porsche Wiesel design.
75/4 and 75/10 Porsche showed 2 wooden mock-up of TOW carrier and MK carrier.
During 76-78 6 prototypes were made.
@Chieftain_armor (1/3)Brief history about Wiesel.
The air-portable waffenträger project could be traced back in 1973, when Bw put KraKa into service and signed contracts with Porsche to do some feasibility research. Porsche recommended a 2.75 ton vehicle and size could fit in CH-53G cargo space.
@Chieftain_armor Would you make a video tour for FVT-02(twin-barrel one) and TVT(giraffe tank), or VTGS(stealth leopard)?
I also heard that Munster have some secret collections, which includes standard tank B gruppe, RU251, AMX 30 prototype A turret, KPz Keiler.
@Chieftain_armor After MBT-70/KPz 70 project cancelled, FRD used remaining PT as experiment testrig, PT3/ET703 was converted to twin-barreled VT 1-2 for DRK(Doppelrohr Kasematt), and ET706/707/708 also took part. AFAIK ET707 involved with mobility-tracks and suspension trials.
Sequences of misfire (Type 90 training material)
When you shot but it doesn't fire, gunner shout "Misfire", keeping LOS to target area while:
Gunner and Commander press firing button of their handles and auxiliary firing switch, repeat 3 times.
