What does it mean "der HKL"?

[Cole Bush]

for example:

"Der Russe konnte vor der HKL aufgehalten werden. "

"in der HKL."

[Holger_Erdmann]

Hello,

"HKL" is the abbrevation for "Hauptkampflinie". In english it is "main line of resistance".

In your case, it can be translated to: The Russians could be stopped in front of the main line of resistance. In the main line of resistance.

Regards,

Holger.

The more common English term for it would be Frontline.
