Command & Conquer: Red Alert 3: Uprising/New Allied Units

Cryo Legionnaire
Cryo Legionnaires are armed with a Cryo weapon with a small freeze radius. Their special ability is to jump a long distance, much like the Sickle's Flea Jump. This can also crush frozen infantry. They walk on water by flash-freezing the sea underneath their boots.

They are trained at the Boot Camp.

Harbinger Gunship
Armed with many weapons this gunship does not need to reload at an airfield. It can be built in infinite numbers and take out many surface targets in seconds. It switches between two different weapons, Proton Collinder-class cannons and miniguns to fit its combat role.

Weaknesses

The Harbingers Weakness is that it is very expensive and it is anti surface only not anti air.

Pacifier FAV
A long range bombardment cannon on a highy mobile chasis, the Pacifier FAV is perfect for decimating enemy bases from long range. Should the enemy manage to close the distance, the FAV can switch to a 7.62mm minigun for close-quarters combat.

Future Tank X-1
A High tech heavy assault tank armed with two weapons to fit its role, the Neutron Cannons and the Riot Lasers.

It's standard attack the Neutron Cannons devastates surface targets at a wide radius while it's riot lasers cut through multiple bad guys including apocalypse tanks.

It requires support against artillery and it requires Apollo Fighter escort against aircraft. ITs weapons may have longer range than the Apocalypse Tank weapons but are slightly inferior.
