DQ's apply to any member with clearance, not just instructors.
The most common are medical issues of a psychiatric nature, substance abuse problem, or financial debt (serious, not normal). These problems put the person at risk of being coerced or blackmailed for information, or the person might go against his/her nature and opt to sell information to deal with their problem. Based on historical experience, anyone who gets into such situations, whether voluntary or not, has their clearance suspended or revoked.
Suspension is the usual step, as the military doesn't easily give up on its members. Revocation is for serious matters or if the person is no longer fit for the assignment the clearance was given for.
