Strecker led his division in the invasion of Ukraine, participating in the Battle of Kiev and the First Battle of Kharkov. He earned another recommendation to command a corps. In January 1942 he was diagnosed with heart arrhythmia and sent on convalescent leave for three months. He returned to active duty in April, taking temporary command of the 17th Army Corps in Army Group Centre and receiving a promotion to General of the Infantry. He commanded the corps in the Second Battle of Kharkov. The commander of Army Group South, Friedrich Paulus, was impressed with Strecker's performance at Kharkov and had him transferred to his 6th Army to take permanent command of the 11th Corps.
