Then:
Attacker can decide to use resilient fighter 1 and attack enemy fighter 2 and both are removed. This means resilient fighter 2 can move any distance left.
Technically, in this case it's actually using resilient fighter 1 to absorb enemy fighter 2's attack, since the resilient fighter 1 has already used its attack for this encounter. This is a necessary distinction because of the example on the page after that about the darkstars fighting the mantas (where each DS only gets one shot at a manta before the mantas can attempt to run, and only get their second shot if the manta's stay in place - thus triggering a second encounter where the darkstars get to attack again).
EDIT: Here's a wall of text that explains what I was talking about in my first post.
Fighters (and anything which functions like fighters) are obligated to "intercept" each time they "encounter" an enemy ordnance marker. For regular ordnance, this just means they instantly and automatically crash into any enemy ordnance they touch, destroying everybody at the same time (in game terms, anyway). So, the precise mechanics of intercepting/encountering ordnance doesn't really matter, because everything gets removed. This is the part that having Resilient Saves chucks out the window.
With saves, fighters might remain on the board for more than one encounter, so it suddenly matters how those encounters happen, and how "intercepting" resolves when an encounter does occur. So what is an encounter, exactly?
An encounter occurs
whenever an ordnance marker moves and that move causes it to physically contact an enemy ordnance marker. However, unless the moving marker is a fighter itself, it may ignore markers in contact at the start of its move (but not at any other point, including if it stays in place - in which case it will interact with those same markers a second time). This is an important type of exception that the game uses in similar situations elsewhere in the rules, such as for ships "moving off" of torpedo markers that stopped on their base.
Each time an encounter occurs, ALL fighters (on both sides) must intercept one opposing marker (assuming they are not intercepted themselves before they attack). Normally, fighters just intercept each other and it doesn't matter who attacks who, but when some are resilient, they may remain on the board and continue to interact. Thus, it becomes important to recognize when a fighter can actually make its attacks (intercept) vs. be intercepted.
Combining our understanding of how encounters occur with the knowledge that a fighter only ever makes one "intercept" attack
per encounter, we can see how resilient fighters are supposed to work. In short, a resilient fighter that passes its save will always have done one of the following in a given encounter:
- Intercepted an enemy and remained on the board.
- Intercepted an enemy then been intercepted itself (or vice versa), and removed.
- Been intercepted and remained on the board.
- Been intercepted twice and removed.
But this isn't the whole story, because in each ordnance phase, BOTH players get to move their ordnance, meaning that resilient markers can "encounter" the same enemy wave more than once in a single phase! This is where you get weird situations like:
1. Two resilient fighters (RF1&2) move into two other resilient fighters (RF3&4). RF1 intercepts RF3, and both pass their saves. RF2 intercepts RF4 and both pass their saves. Then RF3 and 4 make their attacks, removing everybody and ending the encounter.
2. Two resilient fighters (RF1&2) move into two other resilient non-fighters(RB1&2). RF1 intercepts RB1, and both pass their saves. RF2 intercepts RB2 and both pass their saves. The encounter now ends because RB1 and RB2 cannot make intercept attacks, since they are not fighters. When they get to move (in this same ordnance phase), they can move away from RF1 and 2 because they (a) are not obligated to intercept (in fact, they cannot) and thus (b) may ignore the marker in base contact at the start of their move.
...BUT! If they stay in contact by not moving, they will be intercepted a second time this phase, because the fighters will get another attack since it is a new encounter.
I hope that meandering gibberish I just wrote makes at least some kind of sense... Like I said, ordnance gets weird when saves are added to the mix.
Cheers!
