Wenn die Panzergruppe steht, schützt sie eine Feuerglocke...

Wenn die Panzergruppe steht, schützt sie eine Feuerglocke in kaum mehr als hundert Meter Entfernung.

Any idea what is the meaning of this sentence? Direct translation of Feuerglocke does not ring a bell for me.

It's a type of artillery fire which protects its own troops.

Makes sense, thanks!

„When the Panzer group is stationary, it is screened by a dome of fire(s) hardly more than 100 meters out.“

Many thanks!
