The MARS 15 is a French light tank prototype that was designed and built by Creusot-Loire Industrie with the support of Renk, SAM, Valeo, and Baudouin cooperations between the 1980s and 1992. It was originally intended for export to replace the now-obsolete AMX-13 light tanks, one of the best-selling tank series in the world with 35 client nations between 1953 and 1985, and forty years of service and remarkable success in France and abroad due to their simplicity and versatility. The MARS 15 was originally shown at the Satory 90 exhibition and then again at Eurosatory in 1992, with an upgraded variant for the final time. However, the MARS 15 failed to meet expectations and was never mass-produced on a large scale, despite having several advantages, such as modularity, and failed to gain international popularity, much like the AMX-40 main battle tank. As a result, the project was eventually cancelled.

Introduced in Update "Ixwa Strike", the MARS 15 is an excellent scouting vehicle. Given its high mobility and low profile, it is easy to flank and scout the opponent for your allies. Close-quarters engagements are not encouraged, as the inadequate armour does not provide sufficient protection against other vehicles. An effective way to play MARS 15 is to focus on flanking the adversary and engaging the enemy from flanking positions on the sides. If players find themselves in a dangerous situation, the MARS 15 carries four smoke grenades that can provide an effective means of evading danger and repositioning.
