The Army report outlined three "contributory factors" to Jaysley's death - including the "significant strain" of a sexual relationship with a married colleague in the last few weeks of her life.
Mason denied he had tried to "manipulate" Jaysley by talking about his own mental health and suicide concerns, while Webber, who is married, declined to answer questions at the inquest.
An inquest heard how Jaysley had called another colleague in tears claiming Webber had pinned her down and tried to kiss her.
It added that Jaysley had no diagnosed mental health conditions and had not sought welfare support from anyone in the Army.
THE Army's handling of a young soldier's sexual assault claim before she took her own life played a part in her death, a coroner ruled.
