Some Finnish weapon additions.
NOTE:
I have not at least yet added much of production weapons/stuff as this was originally supplementing other Finnish suggestion post but apparently necroing is bad even when its supporting an existing suggestion post, enlisted forums are weird af and barebones.
Suomi KP with muzzle device.
Export Suomi-KP Pre WW2
Swedish license variant, chambered in 9x20 Browning Long
Mosin M/27 Pystykorva with soviet PE rifle scope
Finnish MG-42 variant chambered in 7,62x54r.
Same as above without tripod and cut open.
L-41 Machine gun prototype 7,62x54r
9x19mm M/44 Pistol
M/42 Suomi prototype
Prototype recoilless rifle with multiple variants one in 46mm firing German rifle grenades, one in 47mm firing modified hafthohlladung 3 shaped charges and one in 50mm firing mortar shells and panzerfaust klein and gross.
Weird rocket launches prototype based on Soviet 45mm carriage (the thing its mounted on, not the tube/gun).
Prototype 75mm anti tank gun 75 K/44, highly unconventional design but still highly effective. It used same ammo as Pak 40 but had higher velocity thus better ballistics than Pak 40.
Test with PzGr 39 APHE, Pak 40: 750 m/s vs 75 K/44: 903 m/s.
Finnish T-34-85 armed with German 7.5 cm StuK 40 L/48
Finnish uparmoured T-50
For Squad you could add Osasto Törni / Detachment Törni, a Jaeger company commanded by famous Finnish war hero Captain (Finnish service), Hauptsturmführer (German service) and Major (US Army), Lauri Törni or later known as Larry A. Thorne.
Also a few semi auto rifle prototypes like L-36, chambered in 7.62x54r, 5 round non detachable mag, 5kg weight, prototype made. And more
