Before the week is out I am expecting to go right up into the firing-line.
To go up the road from here to the firing-line is a great experience.
The other day I was ordered to visit a certain battery in the firing-line.
Garrison had been on the firing-line for so long that his nerve was frayed to ribbons.
He had come in from the firing-line, and had incompletely dodged a stone.
It is probably impossible to have them playing close to the firing-line.
But it was too late; all the rifles were in use in the firing-line.
From Caribou Ridge the Turks could enfilade parts of our firing-line.
Ordinarily a man is much safer on the firing-line than in the rest dug-outs.
I found the firing-line, as one usually does, with surprise.
