Star Wars Galaxies TCG

Please, I need help with game rules:

strikethrough
Whenever combat begins involving one or more of your combatants that
have strikethrough, you get +1 total attack.

evasion
Whenever combat begins involving one or more of your combatants that
have evasion, you get +1 total defense.

are those abilities stack?

If I have 3 units with Evasion, do I get +3 bonus to defense, or regardless of how I have units, I get only +1 to defense. The same with striketrough?
