The USA can increase the rate at which its units gain veterancy by purchasing the Advanced Training upgrade.

Some units such as Red Guards and Technicals can be produced with an automatic veterancy upgrade through a General's Promotion. Elite and heroic units have the ability to self-heal. Like in previous games, promoted units gain increased damage, armor, speed, and rate of fire. Veterancy is earned based on the value of enemies destroyed, as in Tiberian Sun and Red Alert 2. Generals features three veterancy ranks: veteran, elite, and heroic. For instance, an elite GI can outrange a Sentry Gun, and an elite Tesla Trooper's bolt can bounce between multiple targets. Also, elite units now gain special improved versions of their weapons. However, these values change once upon reaching Veteran rank, and promoted unit gains a 10% bonus to damage dealt, a 20% increase in speed, a 50% increase in armor, and a 40% higher rate of fire. Promoted units continue to benefit from increased damage, armor, speed, and rate of fire, as in Tiberian Sun. Commanders must evacuate/unload infantry to make them able to be promoted. In the expansion pack Yuri's Revenge, infantry garrisoned in structures and loaded onto units like the Battle Fortress can also gain veterancy, but those who are loaded in an IFVs cannot be promoted since IFVs' weapons change according to infantry they carry while the IFV itself still does the actual firing, not the infantry (the same principles are used in Red Alert 3 and Uprising). The Allied Spy is also able to infiltrate an enemy Barracks or War Factory, giving an automatic promotion to veteran rank for all newly-produced infantry or vehicle units, respectively. This effect covers a 3x3 area around the crate, so multiple units (up to 9 tanks or 27 infantry) can be promoted at once.

Alternatively, a crate can be picked up, and has a chance of giving one free level of veterancy. To be promoted through combat, a unit must destroy one or more enemies with a combined value greater than three times its original cost. Just like in Tiberian Sun, there are two ranks of veterancy: veteran (denoted by a single chevron) and elite (denoted by three chevrons). However, units gain veterancy much faster, and benefit from it more. The veterancy system in Red Alert 2 is similar to the system in Tiberian Sun. The Cyborg Commando, Ghost Stalker, Umagon, and Mammoth Mk.



Units in Tiberian Sun and Firestorm have two levels of veterancy: veteran (signified by two vertical golden bars in its selection rectangle) and elite (signified by a golden star).
