Back from grave... without hope: I just stopped drawing profiles, sometimes try to get something back, but not on bigger scale. This one have some time:
Backstory: generic IFV project from late 60ties. Based on longer Strv-103 hull with gas turbine and diesel replaced by soviet flat opposing piston diesel.
"TG-6". APC version, used mainly as a command vehicle, mortar carrier, or base for other special versions.
"BTG-6": IFV version. Crew: driver, and gunner/commander in single-person turret similar to AAV-7 turret. Armed with 23 mm automatic gun (like used in Shilka), can externally carry single ATGM. Inside would fit 7 soldiers: one behind driver, and 6 in 2 rows, sitting face to face.
BGR-6: Combat Recon Vechicle. Two-crew turret with same 23 mm gun as IFV. Additional 4th crew member, radioman, or special equipment operator (like WMD detectors) can be placed right of driver (where commander sit in real-life Strv-103, or turret is placed in BTG-6 IFV.). Place behind turret with back doors is retained for carring small infantry team, or additional supplies.
WPP-6: tank destroyer. Turret based on BGR-6, with box carring two ATGMs on left side, that can be reloaded from inside. Features of CRV version (possibility for carring 4th crew member, back doors) are also in this variant.
