I read that one typical German division in 1939 has 17734 soldiers let's say 18.0000

1, Trupp (section) - a small group dedicated to specific tasks, eg Nachrichtentrupp - a communications unit attached to the battalion headquarters, permanent (Funktrupp - radio branch) or ad hoc (Aufklärungstrupp - branch / reconnaissance patrol)
2, Gruppe (team) - the smallest fixed unit in infantry formation, usually composed of 8 to 12 men under the command of a senior lieutenant or non-commissioned officer; Her biggest weapon was a machine gun or two ranks on which all tactics were based; It was sometimes used as a shortcut for Kampfgruppe
3, Zug (platoon) - composed of 3 teams and a staff, commanded by a senior non-commissioned officer or junior officer; The light mortar was the main support; Zug artillery consisted of two guns, usually two platoons consisting of batteries; Armored troops consisted generally of 5 tanks
4, Company (company) - composed of 3 platoons and a staff, commanded by Oberleutnant or Hauptmann; In the field artillery, the Kompanie was a battery, under the command of Hauptmann; the companies were numbered in Arabic numerals in a regiment; In armored companies the company consisted of 4 platoons and a staff
5, Batallion (batalion) - The battalion consisted of 3 companies and a support company (a smuggler company) with machine guns and mortars and a staff with a small communications and supply department; In the artillery, cavalry and armored forces, the term Abteilung was used; In 1941 Panzerabteilung consisted of 3 light and 1 heavy companies (suitably equipped with Panzer III and IV), a reconnaissance unit from Panzer II and a commanding officer tank; In standard artillery Abteilung consisted of 3 batteries, including 12 guns, usually commanded by Major, occasionally by Oberstleutnant; The battalions were numbered in Roman numerals in the regiment; Separate battalions (assigned to, for example, divisions) were numbered with Arabic numerals, corresponding to unit numbers of units
6, Regiment (infantry) - consisted of 3 battalions, a support company and a staff, while in artillery of 4 Abteilung (3 light and 1 heavy); The regiment consisted generally of 14 companies, 12 in 3 battalions (9 infantry, 3 support), an anti-tank company and an infantry company as support for the entire regiment; usually led by Oberst;
7, Brigade (Brigade) - in 1941 it consisted of 2 regiment of motorized infantry in armored divisions; usually led by Oberst or Generalmajor; The war was becoming increasingly rarer
8, Division - consisted of 3 regiments and regiments of artillery - infantry divisions or brigades, regiments of tanks and artillery; usually commanded by Generalmajor, or Generalleutnanta; in the German army it was the smallest unit able to operate independently, without additional support; It also included Panzerjägerbatallion, Aufklärungsabteilung, Sappers and smaller units: military post,
9, Korps (corps) - a group of 3 to 4 divisions with their own staff; the corps of the Corps was subjected to much more communications units than the division staff and had a much larger role in supplying subordinate units; Except for divisions, Heerestruppen could control individual units; usually commanded by Generalleutnanta:
10, Arko (Artilleriekommandeur) - independent artillery command with numerous support units (communications, fire management) to control artillery units at supra-level for better fire concentration; usually about the status of a division or brigade; most often assigned to the corps or army;
11, Armee - A group of 2 or more corps, usually commanded by General der (insert type of weapon, eg Kavallerie) or Generaloberst, army staff had numerous units of communications and provided logistical support:
company of tanks - is about 20 tanks
My question is: How can we interpret one unit of infantry in this game? How many soldiers are in one unit for example infantry ? What is the scale of the units?
Please help and answer.
