Maybe the soldiers should sing lullabies over loudspeakers during the night.
I have a better idea. Every CO out there orders their chopper units to blast ride of the Valkyries over loud speakers during the hours of midnight, 4AM and a carpet bombing at 4PM during Mecca facing hours. Now that is how to fight a war.
Forget lullabies, how ‘bout “Onward Christian Soldiers?” That’ll help everyone sleep. ;)
