HOLTON, Kan. (AP) â€” Now roaming the nation's heartland: British soldiers. But, like the Beatles four decades ago, these British invaders are friendly. Some 200 British army and Royal Marine officers are currently in northeast Kansas, training and building relationships with American officers they are likely to see again. "It's all about developing skills, knowledge, attributes and motivation for the troops," said Maj. Jo Bell, spokeswoman for the British Defense Academy traveling with the officers. "It's all about building up their confidence." This is the second year the British have conducted exercises near Holton, about 30 miles north of Topeka and an hour from Fort Leavenworth. The officers did similar training at Fort Benning, Ga., when the program began four years ago.
