strategic advantage

see corporal? this is what I've been telling you.
what's that, sir?
that he who holds the high ground controls the battle.
this is certainly high ground, sir.
yes indeed. we'll see them coming from far away.
unless they sneak up behind us, right?
what? oh. yes. naturally. unless they do that.
my confidence level is high, sir.
er, yes. mine too. nevertheless. . .
check the rear flank?
can't be too careful.
just a formality, sir. I'm sure.
I'm sure.
