f Crono was a playable Commander in a Real Time Strategy Game

Another things to add:

There can only be a limit of 4 Field Commanders on the field

Sentinel Pylons act as basic defense and primary add in Teleport fields or Healing

Combat Fields come in many forms(Support, Utility, Offensives and Defense) but Crono can only have 4 of each time, to use a different field he need to spend time he need to get and replace on of his field types

(EX: Aura Heal -> Aura Heal V2 ==> Weaken Field >>> Aura Heal)
You can switch back to one of the fields as each one is unique


Vanguard Units are the same as other but with Higher Cost with Increase Stats
Ex:
Default Trooper Vanguard Trooper
HP-50 HP-70
Speed- 2 Speed- 3
Damage- 6 Damage- 6
Cost and Time- 50/20s Cost and Time- 75/25s
