... played a crucial role in shaping future U.S. tank designs by addressing key design challenges, and the program itself would grow to dominate 1950s American conceptual tank design.

The M-1 was one of seven medium tank concepts put forward, and was the most conventional of those designs. It was comparable in performance, size, and armament to the T48 Medium Tank. The Question Mark concepts, though originally never intended for production...

It would have probably faded into obscurity if not for a single surviving drawing of it.

One such project was the Finnish attempt to repurpose a Soviet BT-7 light tank into an armored personnel carrier (APC), designated the BT-43. Initiated in 1943, the project produced only one prototype before it was swiftly abandoned.

...the acquisition was cancelled and the Peruvian Army had to keep using the ancient T-55 and AMX-13.

The MBT-2000 that ‘’won’’ the competition did not even meet the basic technical requirements laid out, nor could it be delivered in time with the needed changes to match it. It would turn out the tanks were not even bought and, after both national and international fallout...

The Peruvian MBT-2000s were a result of a program to match the Chilean Leopard 2A4s and to replace the outdated T-55 and AMX-13 tank fleet of the country. However, the process would be troubled with corruption and tampering with requirements.

But, as virtually nobody knew about the acquisition, the ensuing fallout was severe. News outlets managed to dig up information on the acquisition process in mere days and would heavily criticize it.

Only a small batch of C2Vs were built before cancellation. With no sense in scrapping them, the completed vehicles entered Army service, where they were eventually deployed during Operation Iraqi Freedom (OIF), the Iraq War of 2003 to 2011.

Based on the M993 common chassis, the M4 was set for full-scale production in the mid-1990s, however, it was not to be. The M4 was one of many prospective vehicle projects canceled during a mass cull of development programs that occurred in 2001.

It was intended to replace the aging M113-based M577 and M1068 ) and provide an automated tactical command post for mobile armored operations. In this capacity, it would work alongside M1 Abrams and M2/M3 Bradley-equipped armored platoons.

these vehicles are equipped with advanced communication systems and other technology to perform the following four primary functions; information gathering, decision-making, surveillance, and data transfer.

Its counterpart was another Praga-designed infantry tank, the P-II-b. Unfortunately, the P-II-a fell short of the requirements, and lost to Škoda, whose Š-II-a became the LT vz. 35.

The company responsible for the LT vz. 34, ČKD, attempted to satisfy the growing appetites of the military by producing the P-II-a, a tracked armored fighting vehicle based on the P-II (LT vz. 34) that was meant to meet the requirements of category II-a, the Army’s cavalry tank program.

The first tankettes were a disappointment and, although the LT vz. 34’s were well-liked, the Army could not afford to stand still, so new requirements were made for the next generation of tanks.

As a result, its role as Spain’s main battle tank was short-lived and overshadowed by its successor.

While it was envisioned as a stopgap measure to modernize Spain’s armored units, the Leopard 2A4 mostly served as a training platform for tank crews and as an introduction to the more advanced Leopardo 2E.
