Light tank (Red Alert 1)

The M60 light tank was the Allied main battle tank of the early. It was the lighter companion of the and entered service earlier than it.

Background
Fast and versatile, the Light Tank was able to outrun all soviet vehicles. Due to its speed it is also easier for it to crush infantry. Although due to its weak armor it wasn't able to prevail against soviet tanks, due to its low price it was easy to mass produce these tanks and deploy them in large numbers. The tank's main weapon is a 75mm gun, which fires an Armor-Piercing Fin-Stabilized Discarding Sabot (APFSDS) projectile against hostile armors; this gun is backed by a co-axial 7.62mm FN MAG machine gun next to it and a pintle-mounted .50 caliber M2HB Browning machine gun by the commander's hatch, giving it a limited anti infantry capability (the machine guns are not used ingame, for game balancing purposes).

Behind the Scenes
The light tank is depicted by two different vehicles. The sidebar image is (probably to show continuity with the Nod light tank) of the M2 Bradley IFV, while in the cinematics it bears some resemblance to the M41 Walker Bulldog scout tank, which is indeed a light tank with a marginally-effective anti-armor ordnance of 76mm caliber and just enough protection against small arms fire. it also maybe a chaffee light tank or a m6o patton, but unlikely because the patton is a medieum tank. The M41's European counterpart would be the AMX-13, which is armed with a high-velocity 75mm cannon.

There is nothing stopping the Allies of this universe from developing a light tank based on the Bradley, either.
