Are you intending for the completed model to be displayed during training or in action in Germany in 1945?
You've used the markings for A Co 739th Tk Bn. That's fine for the period when 739th was a fully equipped CDL Battalion at Camp Bouse in the Arizona desert or during their brief time in Britain (or the period of total inactivity they spent on the Cherbourg Peninsula from Aug-Sept 1944).
However, 739th was redesignated as Mine Exploder Bn in Oct 1944, a role they undertook until March 1945. At that point, C Company commenced training with DD tanks and B Company began re-training with CDLs in advance of the Rhine crossings.
So - the only 739th CDLs to see action in March and April 1945 belonged to B Co. and they had been returned to depots by mid April 1945.
These are the notes I made a few years ago - summarised from the 739th's AAR.
"On 11th March 1945, two Companies of the 739th were attached to XVI Corps to receive training. Company C commenced training on Sherman DD Tanks whilst Company B began re-learning the intricacies of CDL operations, all in preparation for the assault across the Rhine.
The capture of the Ludendorf Bridge at Remagen on 8th March had been an unexpected bonus, but it did not stop planning for a major river crossing operation later in the month. By 23rd March, Co. B was ready for deployment and provided 15 CDLs to support the construction and protection of a pontoon bridge at Wallach, along with three associated protective booms.
A further operation in support of 289th Infantry Regiment was planned for 1st April. Thirteen CDLs and five M4 'fighter tanks'* were assigned to the mission whose aim was to seize no less than five bridges crossing the Dortmund Ems Canal near Heinrichenburg. The operation was unsuccessful and the CDLs returned to their start point. They were however used later in the month to support bridge building operations over both the Dortmund Ems Canal and the Lippe River."
* Each CDL platoon consisted of six CDLs and two standard M4s, operated by the platoon commander and his Platoon Sgt. The British had long ago found that the Platoon (Troop) leader struggled to coordinate his unit and operate his own lamp at the same time, so they were issued with a normal tank instead.
