The diagram represented above shows an example deployment centred on the German 16th Division, which is composed of the 6th and 52nd Brigades and is part of the German 4th corps.
The other division in the German 4th Corps is the German 14th Division, which is to the right of the 16th, while the US 12th Corps is on its left flank.
A: The actual frontline (known as FEBA - Forward Edge of the Battle Area) is marked by a series of arcs, the convex part of which faces towards the enemy.
B: This is the boundary between the forward left brigade of the German 16th Division (in the case the German 52nd Brigade) and the forward right division of the US 12th Corps (in this case the US 6th Division). Therefore, the symbol is shown for the larger unit, in the case the US 6th Division. So the designation 'Div' is not placed next to the '6' whereas the full title of the German 52nd Brigade is put opposite. As the two units are of different nationalities the nationality designators are used.
C: This boundary is the inter-divisional boundary between the two divisions that make up the German 4th Crops, 14th and 16th. The same method is used as in B but because the two units are of the same nationality, there is no need to indicate this on the diagram.
D: This is the inter-brigade boundary for the two component brigades of the German 15th Division (52nd and 6th). This there is no need to mark them with 'Bde' or (GE).
E: These are the rear boundaries of the two brigades. Thus, it is necessary to mark the boundary with the symbol for whichever unit it is. They therefore show a brigade symbol, rather than a divisional one, although the rear are is marked to show '16 Div' (as it is the division's rear area) but without having to have a nationality designator as it is all German.
F: The is the continuation of the inter-corps boundary between the German 4th Corps and US 12th Corps, (as represented by the US 6th Division) from B. It therefore follows the same rule a B and uses the symbol for the larger unit, in this case the US 12th Corps, and spelling out the designation of the unit on its respective side, in this case the German 16th Division. Again, as the units are different nationalities, the respective designators are show. As the map is concerned with the deployment of the German 16th Division, the rear boundary of the US 6th Division is not relevant and is not shown.
G: This is the inter-divisional boundary between the two component divisions of the German 4th Corps. The boundary is marked with a divisional size symbol as they are both divisions and only the unit numbers are shown, as their size and nationality are the same.
H: This is the continuation of the inter-corps boundary from F. As it is the corps rear area for the German corps, the corps symbol is used as are the nationality designators, but the word corps isn't.
J: This is the rear boundary for the German 16th Division, so the divisional symbol is used but the word 'corps' is used to qualify the '4' although the 'Div' qualification and nationality designators are not used.
