Still working on Widening the Corridor as time permits.
A great source for modding is the digital collection at the Combined Arms Research Library at Fort Leavenworth, Kansas: http://cgsc.contentdm.oclc.org/cdm/
One of the units I have added is the 402nd Field Artillery Group, two 155mm gun battalions and an 8 inch howitzer battalion. I haven't even started looking at the German side, but I find that attached American artillery is often lacking.
Anyway, for the heck of it, I decided to add an artillery group HQ. From what I could discover, it was roughly similar to a divisional artillery HQ, so that's how I set it up. As near as I can tell, the AI Corps and divisional HQ units have no idea what to do with the artillery hidden under this subordinate HQ. At least,I never see them firing, and they always seem well rested. OTOH, if I want to drop a load of hurt on an objective or an enemy attack, all I have to do is issue orders to the group HQ and the subordinate battalions will fire away with considerable effect.
I'm still not sure how I plan to use this "feature" in the future. A two battalion group was attached to the 11th Armored Division, but the employment of those weapons may best be left to the AI, so no group HQ in that chain of command. I'll probably save it for Corps level groups since I am making his decisions for him.
I have added a few other units to the US OOB. CCA 6th Armored appears in Bastogne on its appointed day to drive on Wardin, per her historical assignment. While staring at a map from Hugh Cole's book on the Ardennes campaign I noticed the 28th Cavalry screening in the line between the 134th and 137th. Funny how so few accounts mention the appearance of Patton's "household cavalry" but I think I have found enough info from reliable sources to add them to the mix.
The two beat up battalions from the 318th have been added to CCA and CCB 4th Armored. I have also added the 188th ECB, which was attached to the 4th Armored at this time. This was a rear area unit, and in this scenario, I find enough Germans in my rear area, that it continues to operate in the rear guarding road junctions and patrolling lines of communication.
I also delete units from time to time. The 73rd AFA was in the oob for the 101st, and my foggy memory couldn't place him at the scene. His after action report is available at the afore mentioned resource, and she was elsewhere with the remnants of the 28th Infantry Division by 12/27.
One more change of note is that I have altered the lines to more closely match the 12/27 situation map for the 4th Armored as depicted in Armor at Bastogne, by Lt. Col. Summers, et. al., and the map of the 101st lines on 12/25 and 12/26 from Hugh Cole's The Ardennes: Battle of the Bulge. So the 101st starts with a smaller area of responsibility and considerably tighter lines. In addition, the HQ's and support units of the 53rd and 37th are now within the perimeter as indicated by the 4th Armor map. Meanwhile, the 4th Armored's front line outside of Bastogne runs Clochimont, Hompre, Hollange, Honville. The start positions for units of CCA 9th have been adjusted and TF Brownfield has been added to her OOB per Lt. Col. Summers.
