SIMPLE ANSWER: KOIRALA IS BAHUN, CAN ONLY TALK .BIG DOUBT IF THEY CAN PASS THE ARMY CADET'S TEST. WILL NEED LOT OF STRENGTH BRO TO BE AN ARMY OFFICER.NOT AS SIMPLE AS ''CHAMCCHA GIRI'' and big talks to be in politics. Why do you think bahun changed their surname as CHETTRI to get into british army in 2nd world war just lilke many newar,tamang and sherpas changed their surnames as GURUNG and THAPA.Why do you see less bahuns in nepal army and police? The answer is obvious Newar are good in business, gurung ,rai ,magar n chettries in the warfare and bravery tamang and sherpas in mountaineering and business but BAHUNs in their ancestral occupation. i.e preaching which is most suitable in dirty politics
