No. Because you declare the Short Movement Skill Move as part of the Assault declaration: Super jump modifies the Jump declaration to be a short skill. Note you could use C+ as part of an Assault, because it modifies the Move skill.
What? Climbing Plus and Super Jump both function in the exact same way to change an Entire Order Movement Skill to a Short Movement Skill. If one works, then so should the other: This Special Skill alters the user's Jump Skill from an Entire Order Skill to a Short Movement Skill. This Special Skill alters the user's Climb Skill from an Entire Order Skill to a Short Movement Skill. If anything, Climbing Plus would be the one that can't, while Super Jump can, since Super Jump actually has the "Movement" Tag attached next to "Optional", unlike Climbing Plus.
@macfergusson Assault calls out the Move skill. Super Jump alters Jump. Jump is not Move, both (become) Short Movement Skills, but Assault requires Move specifically, not just any Short Movement Skill. Climbing Plus on the other hand alters the Move skill and allows you to climb without the Climb skill. That's why Climbing Plus works with Assault.
This, interestingly, is different to Dodge and Guts which just use any Short Movement Skill. Because consistency, it's not a thing :)
Where does it say that? I quoted above the first line of both rules that are using precisely the same language when talking about altered skills.
If that is how this is meant to be interpreted, Super Jump and Climbing Plus should not be written in the same way. The second line of Climbing Plus doesn't say "You declare Move instead of Climb when on vertical surfaces" it says you declare movement AS IF you were on the ground. This is not the same thing.
Effects bullet three, not bullet two: Climbing Plus allows its user to declare other Short Movement Skills or Short Skills (Move+ BS Attack, for example) while moving along or holding onto a vertical surface. That said, I think Assault wouldn't be allowed because it's not a Short Skill.
Somewhat related; what do you think the chances are we can get an FAQ on whether Assault is its own movement skill or if it is using two actual Move? I'm thinking both this topic and Domaru in mixed link teams.
Difficulty is that Assault would be declaring a Move that the non-Assault models can't perform. So not only is it not a regular Move+CC (among other things, both the unusual length Move and the CC get declared before the first round of AROs.). Because the Assault models are declaring them as part of the Assault skill.
There's an example on the climbing plus page that reinforces that you can start on flat ground, declare move, and go up onto a wall. http://infinitythewiki.com/en/Climbing_Plus A Reaktion Zond, a Nomad Remote with the Climbing Plus Special Skill, declares the first Short Skill of its Order: Moving from its position to the top of a nearby wall. The Reaktion Zond (MOV 6-4) moves 2 inches horizontally to reach the base of the wall and climbs up his remaining 4 inches towards the top. As I've said many times in many places, the fact that C+ and SJ are different in this regard is incredibly unintuitive and frustrating to me.
@ijw yes but Assault is made up of the Short Movement Skill Move. So it consists of a skill to which C+ is applied.
I'm declaring an Entire Order skill while on a horizontal surface and Moving over a vertical surface as part of that skill (using C+ to modify the Short Movement Skill Move that is called out as part of the Assault).
So no jumping from walls then? (Without Super-jump that is). No spec fire, nor suppression fire whilst on walls? (That makes my Wulvers sad).
The idea that you can incorporate climbing plus into Assault some times but not others is even more inconsistent.
What is inconsistent is allowing most but not all order to be possible while you are standing on a wall with C+ as if it was a horizontal surface. Why can you move but not cautious move ? What if you started Cautious Move on the ground, can the path make use of your ability to walk on walls ? It is in the same vein as using Assault while on a roof, and then use a path that goes down the wall instead of down the ladder/staircase.
No, not being able to use Entire Order skills while you are Climbing if you have Climbing Plus would be entirely consistent with existing Climb rules. Was it the right call? I'm not sure about that. But that doesn't make it inconsistent. My point was that if you can't use Assault when starting on a vertical surface, it wouldn't make sense to then be allowed to use Assault when starting on a horizontal surface but then using Climbing Plus to move up a vertical surface. It should be either Yes or No to mix Assault with Climbing Plus, not half-and-half-maybe-sorta-kinda-sometimes.
No: I'm arguing that you can always incorporate C+ into a valid Assault. @ijw reminds us that you can't declare a valid Assault while on a wall.
