A 90mm anti-tank gun put on tracks. That's pretty much the gist of this vehicle.
Well, it's also light enough to be air-dropped, so there's that.

Service-wise the Scorpion hasn't been used in many wars; besides the Vietnam War where it was used for a while by one specific airborne brigade (before being replaced by the Sheridan), the only other time the Scorpion got used was during Western Sahara War* by Moroccan forces against opposing forces. The main role this vehicle served was fire support, as being an unarmored vehicle meant it was better off keeping its distance from the thick of it. Not a lot of info about how well it performed in that role; it probably wasn't entirely a bad vehicle, but I wouldn't be surprised if the crews of the vehicles didn't care much for the lack of any meaningful cover, especially if the enemy decided that they and their mobile gun needed to go. Sure, the Sheridan had its own issues, but it was fully armored and had a rotating turret, which were things the Scorpion just didn't have.

Also, a morbidly funny thing; should the Scorpion needed to shoot at something from the gun's far right traverse, the commander would have to abandon the vehicle...because if he didn't, he's getting a breech block to the face when the gun fired. Big oof.

This post was kinda rushed I feel, but then again, it's one of those "barely saw much service" kind of vehicles. Two wars, not a lot of information about whether it did it's job good enough. Tanks Encyclopedia does have some background information regarding its development, but even that article is quite sparse compared to most of their other entries. Either way, I'm not dead, and I wanted to post something after not existing for several weeks. Next post will be covering the first pilot model of the MBT-70. Till then, cheers!

*One of those wars I never heard of until I was doing some recap/research on the vehicle I'm posting. It spanned the late half of the Cold War, and was basically a consequence of Spain leaving it's territorial possessions along the West African coast during the mid-late 70s. No clear victors, as currently the Western Sahara is still technically its own thing, though Morocco currently occupies a majority of it.
