Multinational corps and formations

[Fuchs]

River crossings demand a lot of planning, especially opposed ones, and you may march 50km in a few hours, but 50km opposed advanced will take about 24 hours or more, based on all the analysis I know of.

Read the book that I told you about today. ;-)

And btw, who opposed an advance for 50 km in a row? Such a depth of defence is admirable and something I'd really encourage (even more, but that's a long story), but you're unlikely to face it unless you're in pursuit and do it wrongly.

How many vehicles in a Brigade? Brigades cannot just break contact and skoot off somewhere. You need to draw back to assembly areas, plan routes, de-conflict convoys on the MSR etc etc etc.

We shouldn't think of brigades as one piece. They're more like a mobile cloud of units.
Their TO&E is furthermore not cast in stone. The byzantine vehicle inventories of modern units are stupid and need to (and can) be changed.

Today's road network density and off-road capability of modern vehicles allows for a great deal of agility & quickness on part of brigades.
The problem are men who haven't been trained to exploit this potential because neither Cold War nor post-Cold War armies have made it a priority.
