M113 106mm Recoilless

IRL

The M40 Recoilless rifles had largely become obsolete by 1985, with guided missiles being far more effective and accurate for the role of light anti-tank weapon. However, by comparison, recoilless rifles were still very cheap, easy to operate, and could be mounted on a large enough vehicle with little trouble. In fact, they could even be locally produced, as the technology didn't require any expensive electronics or programming; they're little more than modified cannons. For this reason, many countries continued using recoilless rifles like Iran.

While the US never mounted the M40 on an M113, they did produce a dedicated six-rifled tank destroyer called the M50 Ontos. This vehicle however was short-lived, so most countries used what they had, like the M113.
