For conspicuous gallantry and intrepidity above and beyond the call of duty at Flamierge, Belgium on 4 January 1945, when his company was pinned down by enemy artillery, mortar, and small-arms fire, two hostile tanks attacked the unit, inflicting heavy casualties. S/Sgt. Jachman, seeing the desperate plight of his comrades, left his place of cover and with total disregard for his own safety dashed across open ground through a hail of fire and, seizing a bazooka from a fallen comrade, advanced on the tanks, which concentrated their fire on him. Firing the weapon alone, he damaged one and forced both to retire. S/Sgt. Jachman's heroic action, in which he suffered fatal wounds, disrupted the entire enemy attack, reflecting the highest credit upon himself and the parachute infantry.
