I have a question about a possible poor usage of the preposition "along" here:
Over the course of the operation, about four million soldiers of the Axis powers invaded the USSR along a 2,900 km front, the largest invasion in the history of warfare. In addition to troops, Barbarossa initially used 600,000 motor vehicles and 625,000 horses.
Would "...invaded the USSR through a 2,900km front..." be better?
is better than:Trucks entered the country along the northern border.
Trucks entered the country through the northern border.
An invasion is more geographically spread out than trucks entering on a highway. They invaded at different places along the border.
Saying the trucks entered the country makes it seem like the trucks were driving themselves.
I agree with SoothingDave- there was a very long front with the Axis invading at various different points. A border is a fixed point which trucks must pass through unless they're smugglers trying to avoid the border crossing, but an invasion enters wherever it wants.
Also, the two mean different things. If there was a blitz like the Schlieffen plan, which saw a highly mobile breakthrough, I would say it was an invasion through that area. If it met with resistance, and was broad, it was along that area.
