Attacking

[PoorOldSpike]

..One simple example without flags: An attacker is given the order to gain possession of a hill... The defender is given the order to just hold the line...

What does "gain possession of a hill" mean exactly?
Why not just plonk a flag on the hilltop so that we'll know for sure who possesses the hill at the end?

And what does "hold the line" mean exactly?
Why not just plonk several flags along the line so we'll know without doubt at the end who holds them?

See, playing without flags means there are too many grey areas, wheras by using flags everything is clear-cut in black and white..;)
