 Which of these is the best explanation for why Read put on his green beret during the battle?
THE GREEN BERET By TOM PURDOM Illustrated by Schoenherr Read locked the door and drew his pistol. Two men with rifles plunged into the gas; sighing, they fell to the floor in a catatonic trance. A grenade arced from the bushes and the pursuers recoiled from the cloud that rose before them. Two types of recruits are accepted by the UN Inspector Corps: those with a fanatic loyalty to the ideals of peace and world order, and those who are loyal to nothing but themselves. No one knew how many times he nearly ran from other clubs, how carefully he picked the safest spot on the battle line. The international cops wore green berets, high buttonless boots, bush jackets. The UN Inspector Corps had been founded to enforce the Nuclear Disarmament Treaty of 1966. Trained to use small arms and gas weapons, they guarded certain borders, bodyguarded diplomats and UN officials, even put down riots that threatened international peace. Read went through six months training on Madagascar. Rather than resign, he accepted punishment which assigned him to weeks of dull, filthy extra labor. One power implied in the UN Charter no Secretary General or Inspector General had ever tried to use. Men planted bases on the moon and in four years, 1978-82, ringed the world with matter transmitters; but the black population of Africa still struggled toward political equality. He began a propaganda war against neighboring South Africa, promising the liberation of that strife-torn land. Most Negro leaders, having just won representation in the South African Parliament, told him to liberate his own country. China called the uproar a vicious slur on a new African nation. The United States and Russia, trying not to get entangled, asked for more investigation by the UN. If he got away with it, some larger and more dangerous nation might follow his precedent. They would enter Belderkan, arrest Umluana and try him by due process before the World Court. If the plan succeeded, mankind would be a long step farther from nuclear war. But then they would have spent hours flying over Africa, with Belderkan fighters in hot pursuit, other nations joining the chase and the world uproar gaining volume. From Miaka they would transmit to the Belderkan Preserve, a famous tourist attraction whose station could transmit to any point on the globe. They planned to get there before it could be defended. "There's no military base near Miaka," Rashid said. He had degrees in science and history from Cambridge but only the Corp gave him work that satisfied his conscience. Without losing any forward speed, the driver took them straight up.

 He thought it would offer him some protection he got shot.  He found some comfort in the familiar uniform.  It was annoying keeping it in his pocket and this was less distracting.  He wanted to make sure others in the battle could identify him, to avoid friendly fire.
