I would like to suggest the Pz.Sfl.II 7,5 cm K. L/41 auf Zgkw.5t (In long Panzerselbstfahrlafette II 7,5 cm Kanone L/41 auf Zugkraftwagen 5 Tonnen.

It would be a unique playstile for the german tree as it combines firepower with mobility at the lower ranks in for of a Mobile Light Tank Rank 3 Br 3.3. It carries a 7,5 cm Kanone L/41 which is a more powerful gun than the 7,5 cm Feldkanone 16 n.A. (Neuer Art). It would be similar in performance to the M3 GMC with the difference in having more armor, a turret and a sligly more powerful cannon.

In terms of History:

Specilized armored vehicles were sent to Libya for Rommel, long befor  D-Day`s funnys. In response of the british heavy tanks.

The story of the vehicles itself begins in 1935, in a report of the Waffen Prüfamt (Wa Prw (?)) from the 30 October 1935 with the title of Offensive Abwehr von Panzerwagen (Offensive defense against tanks). On the 11 July 1935 at the demonstration at Kummersdorf the Oberkommando des Heeres emphasized that a offensive tank defense must be strived for. With the example that you dont use a heavy bomber against a heavy bomber, but a fast figher with the fitting armarment, the conclusion was that a fast and nimble vehicle with a powerfull gun was needed. The 2 main charactersitics was Speed and firepower. The third was armour, as long as it doesnt conflict with one of the first two or both.

The exact 8 points needet were:

1. very high road speed to achive good operational mobility.

2. good cross-country mobility, at least the same as tanks.

3. cross-country speed and maneuverability greatly superior to a tank.

4. small target area.

5. good fireing platform for accurate shooting while stationary.

6. weapons capable of target destruction at rangers of 700 meters up.

7. cheap and quick mass production in comparison to tanks.

8. if possibly achivable without interfering with the first seven requirements, rapidly dismountable weapon for the purpose of employment in the same way as towed anti-tank guns, as well as rapidly remountable.

The 7,5 cm K L/41 was choosen with the possibility to fight against heavy french tanks such as Char 2C, 3C and D, with capabilities greater than the 7,5 cm FK 16 n.A. (Feldkanone neuer Art) (which fired the K.Gr. Rot Pz at 650m/s.)

 

By the Aberdeen Proving grounds and a mention in a book, it turned out that all guns, L/33, L/34,5 and L/41 all have the same casing ammo (75x495mm) as the L/43 and L/48 have, sharing the same ammo and breech (for the creation the Pak 40 got the L/41 breech) and by that no problem with ammo supply was created, cince it used normal 7,5 cm KwK 40 L/43 ammo, which would later come into main production.

 

Designed: 1936-1941

Manufacturer: Rheinmetall-Borsig

Number built: 2

Mass: 11 ton 

Crew: 4

Armor: 5,5 - 20mm

Hull  front 20mm/10°

Turret front 20mm (For the turret the Gun mantlet and the straigt plates are 20mm/50°to the back makeing it 30mm aquivalent and the half circle at the back is 14,5mm)

Hull and turret sides 14,5mm/10°

Hull rear 10mm

Hull roof 10,5mm

belly 5,5mm

Main armament: 1x 7,5 cm Kanone L/41

Traverse: 360°

Vertical: -8° to +20°

Reload of 5 sec/shot, cince it is based on the FK 16 n.A. which had up to 12 rounds/min

 

Gun Specs:

K.Gr. Rot Pz:

Apcbc

75mm 6,78 kg 685m/s 80g (102,04g) Fp.02 and Np.10 with a wopping penetration at 10m of 118mm

Sprgr 34:

He

75mm 5,74kg 485m/s 686g TNT 10mm over all

K.Gr. Rot Nb.

Smoke 6,2 kg 485 m/s 50g smoke stuff, its smoke dont expect much against armor.

Gr. 38 HL/B Heat 4,57 kg 450 m/s 872,1 g tnt aquivalent 80mm/0°

Gr. 38 HL/C Heat 4,8 kg 450 m/s 875,5 g tnt aquivalent 100mm/0°

Then there are some other rounds like Kartäschen (Canister shot) but they arent represented in game, the gun can use the same ammo like the 7,5 cm KwK 37 L/24, as it is a quiet early vehicle and not SO High velocity it probaply never got Pzgr 40 (but i dont know in the end.)

Engine:6-cylinder water cooled Maybach HL 45 150 hp

Maximum speed: 50 km/h (31 mp/h)

So a Pz2 and a truck had an intimate night together?

 

The vehicle would be a perfect Event reward. Since it was just a proto.

A lot better then the current BP event reward. Sd.Kfz.251/22 that was made in 1000+ vehicles.

Not exactly, its name is Pz.Sfl II because it is an armored halftrack and the 2 model.

If you look at the pictures.

There are many details that reminds of the Pz 1 and Pz 2 tanks.

That's why said "Pz2 and a truck"  Just thought it looked like it :)

 

I know it's not based on a Pz2.

I have noticed the 75mm Type 3 Gun on the Chi Nu has ballistic wise a slightly weaker gun but i thing would feel the same.

This could also be put at Rank III as a light Tank similar to the M18 (which is also a TD) and Br 3.3 or so.

Decent gun decent speed bad armour sounds like a rank 3 light tank candidate to me. Since the m24 is 3.7 I would put it around there. It does lack a roof so maybe slightly lower.

Added the new TnT aquivalent of the Fp.02 und Np.10 with 102,04g makeing the after effect even greater, perhaps this would be the most deadliest gun in its class compared to similar russian 76 and american 75mm guns. Having more penetration and more filler as well as higher velocity.

This would be a very nice Rank III Light tank Br 3.0-3.3
