1) Several divisions were raised/rebuilt as larger Typ 1944 Infantry Divisions, then re-christened VGD.
2) Manpower sources for the VGD were: "experienced troops" from shattered divisions. These were often support personel, not front line troops; new men, age 16-60, some with only 5-6 weeks of the shortened 8 week training period; Luftwaffe and K-marine personel, some receiving only 2 weeks infantry training; conscripts: Hungarian, Austrian, Poles, Alsacians etc, who may be suspect or untrustworthy, and Hiwi: former Russian and Ukranian POW's who switched sides to receive better treatment, and were likely to flee as soon as shots were fired.
3) Equipment: 74 divisions were formed from 6/1944 to 10/1944. Not enough equipment for all. Several divisions were formed, and sent into combat without their PzJgrAbt.
