Not unless you want them to behave as a radio button cluster, or otherwise
want them in a group for whatever reason. (What part of the docs are you
looking at? It sounds like something was confusing and may need to be

You can run through each button in a repeat loop:
repeat with x = 1 to the number of controls of group "grpButtons" of
delete control x of group "grpButtons" of stack "Map"
If you decide the buttons don't need to be grouped, you can repeat over the
number of controls in the stack, and delete the control only if it's a
button (or use whatever criterion you need to make sure you don't
accidentally delete objects you want to keep):
repeat with x = 1 to the number of controls of this card of stack "Map"
if word 1 of the name of control x of this card of stack "Map" is "button"
then delete control x of this card of stack "Map"
