Rulebook says about Suppression:

"The most common way for a unit to gain suppression tokens is
to be the target of a ranged attack. After a ranged attack, ..."

Rules Reference, instead:

"After an attack, if the attack dice produced at least
one hit (x) or critical (X) result, the defender gains a
suppression token."

As far as I know, I believe that Suppression Tokens are distribuited only after ranged attacks, but since that 's not mentioned in the Rules Reference my group have some doubts abut it...

What do you think?

EDIT: sorry I've seen that is already discussed in another thread. Please cancel it.
