Is it permissible for a father to marry his daughter to a volunteer in the Syrian regular army, and what is the ruling on this marriage? What is the role of the young man asking the question in this matter; should he remain silent or speak with his uncle, clarifying the ruling of Sharia, or is he entitled to propose to the girl if the first suitor is rejected?

If the suitor is a Nusayri, then he is a disbeliever, and it is not permissible to marry him to a Muslim woman. This must be clarified to the woman's guardian. However, if he holds the beliefs of the Sunnis but supports the Nusayris, it appears that he is not deemed a disbeliever, and it is permissible to marry him, though he is a transgressor (fasiq). The woman's guardian should be advised to marry her to a righteous man. As for proposing over the proposal of this man, if he is a transgressing Muslim, there is a difference of opinion. The correct view is that there is no difference between a transgressing suitor and others. If the woman does not incline towards the suitor or rejects his proposal, then there is no harm in proposing to her.
