Reposted from my upgrade project, could do with some touching up and some new models making to be honest, but its still very relevant to this thread:
The AMS I would adapt to serve support troops in a variety of roles and they would be accessible with the relevant advanced support certifications.
The dedicated support AMS variants would be:
Medical AMS: Standard AMS as it is now; a place for respawning. It would also have the ability to heal troops within a few meters, as well as increase stamina regeneration.
Vehicle Repair AMS: Equipped with a vehicle repair bank and resupply station. No infantry respawn ability.
Command AMS: Equipped with a command uplink and radar dish. No infantry respawn ability. This vehicle would allow the commander to access RTS style controls to direct his platoon when piloting a command drone from the vehicle, and view his troops HUDs via helmet mounted cameras. They would also be able to access their command tools whilst inside the vehicle. All spotted enemies would be highlighted on the commanders screen.
Hacking AMS: Equipped with a various pieces of equipment for the hacker to utilise to disrupt the enemy. No infantry respawn ability.
The HAMS would allow the user to do the following:
1) Disable Enemy Radar - the HAMS allows a user to disable the radar of all enemies in the area.
2) EMP Strike - Like an Orbital Strike, but with EMP. Similar to the CUD's EMP ability, except small (CR3 size, no bigger) and able to be triggered remotely instead of locally. Cooldown period of 5 minutes.
3) Scramble Lock-On Devices - the HAMS has the ability to broadcast a lock-on jamming signal that is of significant size if triggered around the HAMS immediate area, or smaller size if activated on a remote target. This signal increases the lock on time of weapons.
4) Remote Door Unlock - Only affects one enemy door. The HAMS has the ability to remotely disable the door lock on one entrance indefinitely. Can only be used on outside entrances, not interior door locks.
5) Disable Shields - The HAMS has the ability to temporarily weaken one of the shields on the enemy base, allowing friendly vehicles to pass through.
7) Increase Hack Timer - The vehicle emits a disruptive field which adds 30 seconds to the hacking process of nearby control points. This is used by defending troops to allow more time for for defenders to retake the control console. Note that this benefit would not stack.
