On a sun-baked plain four hours' drive south of Kathmandu, the capital, a platoon of Maoist fighters in jungle fatigues is on the move. A cry of "lal salaam!" ("red salute!") pierces the air as the drill instructor orders a halt, and the soldiers make thrusts with their mock-up wooden rifles. Even in the haze of dusk, it is clear there are still two armies in Nepal.
