As "repulsor vehicles may move onto impassable terrain" and they can carry and drop objective tokens in Bombing run, can they drop objective tokens completely within an impassable terrain? In the section on barricades, it is said that no objective tokens can be placed on them, but this is not mentioned in the impassable terrain section. Thank you.

In this paragraph, what does "a straight line through terrain parts" means exactly? If all other conditions of cover are met: Case 1: 501 and B1 is on the same terrain part at the exactly same height (also, the same elevation). They both have a hunker token. When they range attack each other, will they gain Cover [2]? Case 2: 501 and B1 is on the different terrain part at the exactly same height (also, the same elevation). They both have a hunker token. When they range attack each other, will they gain Cover [2]? Case 3: 501 and B1 is on the different terrain part at the different height (but within range 2, which is the same elevation). They both have a hunker token. When 501 range attack B1, can B1 gain Cover [2]? Also, does Open terrain grant a character cover? It does not specific Blocked terrain in the cover section of the rule. Thank you.

Hi, Aggressive says "After an attack targeting this character is resolved, if the character suffered [damage], it may advance S towards the attacking player." Does it means: A: Attacker cause damage to Crossbone, so this innate ability triggers. OR B: A attack targeting Crossbone is made but cause no damage. However, there is one damage token on Crossbone, so he 'suffered damage', then this innate ability triggers. Which one is correct? Thank you so much.
