Is there an explanation?
Yes, the other elements of the division appear independently. A search in the scenario design section should yield posts with lots of details and rationale.
Okay, I did do some more research and found that all of the brigades do show up at Aden.
A shame you cannot recombine the unit. In my future games I may delete those 3 brigades and make this a 'proper' division.
It would be great for shoring up Burma/India
Is has high EXP and comes in fully formed and has a metric ass load of artillery tubes and engineers. It would be nice to have it in place to stop the IJA coming up the coastal road in what is today Bangledesh.
I think AndyMac did the UK units. There was an extensive discussion at the time regarding the 70th. Afaik, the reasoning behind not being able to recombine the unit is that the 'hq' unit and one of the brigades withdraw. The brigades work well as ersatz air-landing units.
The problem is using future real life events to control what should be a player choice.
70 Division should be available for use as a standard British Infantry Unit, alternatives are to have the 3 Bdes, Recce Bn & HQ capable of forming a standard British Infantry Div, IFF the Allied player chooses, he could have the Brigades remain and change to a LRP TO&E. Not have it forced upon them.
What if the war doesnt run as IRL and you want to have 70 Div defend Pert or Sydney or, in CR World, invade Hokkaido???
