On a unit or support cards, once an ACTION has been triggered can it be used again, if desired, the next turn, or is it one and done?

This was covered in your previous thread.

The action of a card in play can be used as often as you like, provided you can pay the costs, have legal targets, and fulfill any other requirements mentioned in the card text. Some actions can only be used a limited number of times, they say so on the card.

Triggered actions are actions with a trigger condition, something that needs to happen for you to be able to trigger the action. This can be a point in time ("Action: At the beginning of your turn …") or a condition ("Action: When this unit attacks …"). A triggered action can be used only once per trigger condition met, and it has to be used at the earliest opportunity after the condition was met.

Mallumo - thanks. Sorry to be redundant. I had some questions right "out of the box", then I think I must have forgot or gotten confused about the answers once a buddy of mine and I actually played for the first time the next night and my brain had to work a little more

Again, thanks for your help.
