It seems people think the Soviets will get the tank. Swedes may not even be in the game from what I know.
There is old video/screenshot evidence for the Swedes, but, as for most of the last Era, we're waiting on Details.
Unfortunately, tanks and the Soviet Union are pretty thoroughly linked in the popular imagination, and with good reason: before 1941, the Red Army had more tanks than the entire rest of the world combined (21,000) and after the war, they mass-produced tanks at a rate several times higher than any other country, including the USA. From sheer numbers, Red Army Tanks are pretty much unavoidable.
On the other hand, the Swedes have (like the Soviets/Russians, if anyone bothered to look) several interesting modern Emblematic Unit possibilities:
Army
STRV 103 Main Battle Tank: being replaced by newer models now, but one of the most innovative armored vehicles of the 1970s - 90s
ARCHER, or FH77BW, a fully-automated 155mm gun-howitzer: combined with the ArtlokRR 2091 Counterfire Radar, this thing can spot enemy artillery shells coming in (up to 100 at a time) and strike back with half a dozen rounds per gun in less than 2 minutes, smothering enemy batteries. Pardon an old artilleryman for getting enthusiastic, but this is an enemy fire support killer!
Air Force
BAS 90 - an air base system based on highways. Developed originally as the BAS 70 in the 1950s, this allowed Swedish aircraft to based almost anywhere in the country and change bases on hours' notice, making it almost impossible to knock out the Swedish Air Force. This would be a whole new capability for an in-game set of air units.
JAS-39 Gripen Multi-Role Fighter - a programmable aircraft, and one of the best Stealth aircraft in the world, which does stealth using electronics and computers rather than airframes. I understand their favorite trick lately is to fly up and come alongside Russian MiGs and wave at them from 100 feet away - and the Russian jet's radar and other systems Never See Them. Good way to require a frequent change of underwear among Russian pilots . . .
Navy
Visby class Corvette: a missile-armed ship you can't see with either Radar, infrared or the Mark One eyeball.
Gotland class submarine. A conventional submarine, but with an engine that uses a closed-cycle heat system that is air-independent, meaning this 'conventional' submarine can stay deep underwater longer than any other conventional submarine in the world, and not requiring the water cooled pump engines of a nuclear plant, is Deadly silent.
In other words, Sweden could have Stealth surface ships, submarines, and/or multi-role aircraft in the game!
