Each German regiment can operate independently, meaning it has a counter to every form of hostile action. For example, an infantry regiment has, in addition to small arms, FlaK units to counter enemy aircraft and PaK units to counter armored vehicles.
According to this documenthttp://carl.army.mil/nafziger/943GXAD.pdf prepared by Nafziger from CGSC, a German panzergrenadier(mechanized infantry) regiment has a total of 9 AT guns and 12 AA guns at full strength. Considering a typical regiment at full strength can number more than a thousand soldiers, how would these support weapons be spaced throughout the front line that an entire regiment occupies?
Are all of these support weapons placed only at crucial locations like bridge crossings, headquarters, and etc? While small arms fire defends the rest of the line?
Regarding AT guns,
When an enemy attacks with armored vehicles, would panzerfausts and panzerschrecks be the first line of defense? Would the battalion or regimental command deploy AT units only when an enemy breakthrough occurs?
I know the terrain can nullify the risk of an enemy armored attack at some points of the line, but combat in Russia occurred often in the wide open steppe.
These are the answers I have considered, but I would like to consult some experts.
