I have one more issue to clear up before I can post. It is in regards to my character's position in the Regiment. I want to insure that the position, you think he is, is the one I think he has. First, let me define a few terms.

[b]Adjutant:[/b] There was a time when I served in an infantry battalion as the battalion's "Adjutant". My official title, was the battalion personnel officer or the S1. Adjutant is an informal title used during formal ceremonies involving the use of a parade ground. The Adjutant or S1 is one of the five primary staff officers in a battalion, regiment, or brigade. The position exists at division, corps and army too, but he is referred to as a G1 in the higher echelons. At that level, the term "General Staff" is used instead of Staff, hence the letter G replacing the letter, S. At battalion level, the Adjutant is a Captain. At Regiment and brigade, the Adjutant is a major. If you intend on my character being an Adjutant, he would be a major.

[b]Aide-de-Camp:[/b] An Aide-de-Camp is an assistant to a General Officer. Colonels  and below do not get the luxury of an Aide-de-Camp. The position is similar to a bat boy in the British Army, but so much more. He is more than just the general's valet. He manages his schedule and runs errands for him too. He also serves as a body guard when needed. A Brigadier (General) would be allowed a 2nd Lieutenant or 1st Lieutenant. A Major General would be allowed a Captain and a Lieutenant General or higher would be authorized a Major. As a Colonel, commanding a regiment, your character would not be authorized an Aide-de-Camp. Since he is a Colonel commanding a regiment and you keep using the term, "Adjutant" I believe you mean the regimental S1, who is a Major. But I have another option listed below.

[b]Operations Officer:[/b] The Operations Officer or S3 is one of the five primary staff officers. At battalion, Regiment and Brigade, the S3 is a Major. At Division and higher, the G3 is a Lieutenant Colonel. The only reason I mention the operations officer, is because during combat operations, the Commander moves with his operations officer. In the infantry we refer to their group as the Jump TOC. TOC = Tactical Operations Center. The Jump TOC contains the Commander, S3, two vehicle drivers, the assistant Intelligence Officer (subordinate to the S2 Intelligence Officer) or Regimental Intelligence Collection Coordinator (RICC) and the Fire Support Officer (FSO) who would be a Major or LTC. The RICC would be a 1LT or CPT. The S2, who is in the Main Command Post is also a Major and primary staff officer. Since the Regimental Commander travels with his operations officer, wouldn't it make sense that they would have formed a bond as well? Usually the Commander and S3 are very close. If everything went to shit, these two would be together. The Adjutant, S1 is way in the rear with the battalion supply officer, S4 (another primary staff officer), coordinating Administrative and Logistics operations to keep the unit supplied with materials and personnel.

So, far you have mentioned the 25th Grenadier Regiment and [i]some other hastily-raised conscript regiments[/i]. I recommend you promote Childebrand to Brigadier General and give him command of a Brigade. Your Brigade will consist of the following units:
25th (Royal Panchala) Grenadier Regiment (60% strength or 2,250 men + vehicles to move the Regiment)
114th Panchala Volunteer Infantry Regiment (755 men)
116th Panchala Volunteer Infantry Regiment (976 men)
76th Anti-Armor Battalion (36 AT guns /w transports)
357th Transport Battalion (vehicles to move the 114th PVIR)
358th Transport Battalion (vehicles to move the 116th PVIR)

If Childebrand were the Brigade Commander, Theuderic, son of Childeric would be either a Major as the Brigade's Adjutant or a Lieutenant as the General's Aide-de-Camp or the regiment's operations officer. If you want Childebrand to remain a Colonel commanding the Regiment, then Theuderic could not be an Aide-de-Camp (LT), but preferably the Regiment's Operations Officer (Major) rather than the regiment's Adjutant, S1 (Major) who would have been more than 15 kilometers behind the Regimental Commander and his Jump TOC when things went to shit.

Does this make sense to you?
