No cowboys, neither

“The subordinate infantry commander has at his disposal only one sure means by which he may secure timely and vital information—infantry patrols. A well organized and properly conducted infantry patrol may operate successfully in spite of unfavorable weather, poor visibility, and difficult terrain. Successful patrolling demands the highest of soldierly virtues. Therefore, the selection of personnel for an important patrol must not be a perfunctory affair. The men should be carefully selected and only the intelligent, the physically fit and the stout of heart should be considered. One careless or stupid individual may bring about the death or capture of the entire patrol or cause it to fail in its mission. The moron, the weakling and the timid have no place in this hazardous and exacting duty.” – George C. Marshall, Infantry in Battle
