The wife of former SAS sniper Danny Nightingale said the family would now take advice from counsel on whether to appeal his conviction for the possession of a pistol and ammunition.
Speaking outside court, Sally Nightingale said: "We're obviously very disappointed with the sentencing, yet we are pleased that Danny will be coming home with us tonight."
Judge advocate Jeff Blackett told Danny Nightingale, who wore his SAS uniform in the courtroom, that his stories about how the gun came to be in his room "lacked credibility".
But he said there were "exceptional circumstances" that allowed the court to suspend the sentence "because of your exceptional character".
The judge also said that "criticism of the prosecution and the Army is unmerited and totally without foundation".
