question:  Which of these is the best explanation for why Read put on his green beret during the battle?
context: 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 UN Inspector Corps had been founded to enforce the Nuclear Disarmament Treaty of 1966.

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. 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. "There's no military base near Miaka," Rashid said.
