Realising the effectiveness of the EMP cannon, GDI researchers quickly developed a mobile EMP emitter. It is a vehicle that releases a less powerful blast with far less range, creating it radially from the vehicle's present location. It is also weakly armored due to the EMP generators it carries. It is effective only to nearby electric devices and vehicles (cyborgs included). However, the Mobile EMP Cannon requires some time to charge before being able to fire, similar to the teleportation method of the Chrono tank from the original Red Alert.
Its design allowed GDI to deploy EMP blasts in areas without GDI bases, which happened at least twice during the Firestorm Crisis. Mobile EMPs were deployed to stop rioters' vehicles ensued after Tratos' death without damaging them and possibly killing the occupant, and were also deployed in the joint GDI and Nod attack on CABAL's core.
During the engagement, GDI used the mobile EMP device to neutralize a cyborg commando guarding two bridges into the territory. The EMP tech has been redesigned and integrated with the shockwave artillery warheads.
Following the Firestorm Crisis, these units were decommissioned and GDI incorporated EMP technology into the auxiliary weaponry for grenadier squads, while Nod often outfitted Raider buggies with EMP coils.
The tank is quite fast, as it must close in on its target before the EMP release can take effect. The EMP weapon requires a long time to recharge. The EMP shockwave hits everything in its (rather short) radius, whether friend or foe. Additionally, it can disable base defenses such as Obelisks of Light, provided it can get within range. Also of note is that while the Mobile EMP is not affected by its own EMP discharge, it can be disabled if caught in the blast of another Mobile EMP or that of an EMP cannon.
Due to its light armour, it is not the most popular unit to use when taking on enemy armored formations. If discovered, it is often destroyed before it can charge enough power to disable anything. However, it is unobstrusive enough to go unnoticed, especially in small numbers (5 is the safe maximum). When utilized by a commander who is both brilliant and sneaky, it can creep right up to the enemy forces and get at least one pulse off before it is discovered; two if he is lucky.
Here are a few tips that will give you the possible decisive edge in offensive battles:
- Keep them away from the front lines and in the shadows
- Swing them around and behind enemy lines if possible
- Slowly move them up while the enemy is distracted with your other units
- Charge them while they are closing in so they will be ready when they reach the enemy force
- Get them out of range after the first pulse is fired; multiple units increase affected area
Keep in mind that vehicles and structures caught within the blast's effective radius are only disabled for a short time (10 seconds at the most), and that infantry are immune altogether. Also remember that multiple pulses will not affect the length of time enemy units or structures are disabled; once the first pulse is fired, it's wise to move the unit away from the battle area to minimize the damage it takes. And keep allied units out of the blast radius, as they will also be rendered inoperable.
Here are a few tips that will give you the possible decisive edge in defensive battles:
- Keep them behind your defensive lines and spread out among the buildings
- Keep them charged if enemy forces start gaining the upper hand
- Fire them as fast as possible and try to keep them hidden until the last second
- Fire the pulses when multiple enemy vehicles are nearby for maximum effect
- Keep them away from heavier vehicles and anti-armor infantry
Mobile EMPs are most effective against long-range, slow-firing ground units and non-defensive structures.
