I have some questions about the squad actions (p. 219):
1st: I do not understand what it means that an action is a free, half, full or re-action.
Let's take the bolter assautl (p. 221) which is a free action. Does that mean, that a mean who announces this action and every marine in support range takes immediatly a free action and makes a charge movement and one standard attack?
And now every marine is left with his own actions which may be two half actions or one full action?
So does bolter assault happen in addition to the normal actions of every marine?
Or take squad advace. It takes a half action.
So does the marine announce squad advance during his action and sacrifices a half action? And at any time out of his turn he is allowed to make a tactical advance as a re-action?
2nd: Sustain Squad Action
I do not fully understand how an action can be sustained. Let's take again the squad advance, which can be sustained (Sustained: Yes). I lookt at it like this:
Space Marine A uses Tactical Advance.
Space Marine B changes from another squad action to tactical advance.
Now Space Marine A ends tatical advance and starts another squad action.
It seems to me that you can sustain squad actions be "giving" them to another fellow marine?
My next problem is the difference between sustained and not sustained:
[...] once an ability has been activated, it remains so for the remainder of the Mission (if the ability is Sustained) or for the duration of a singel combat (if the ability is not Sustained) [...]
Does that mean, if a squad action is listed with Sustained: No then this action can be used the whole combat but afterwards it is over? And must be repaid with cohesion at the start of the next combat?
And other actions which are listed with Sustained: Yes, they are active as long at least one marine uses that action? The whole mission?
