you are right. people join nepal army for mostly prestige. people from remote places of nepal and people who do not have much opportunity join it for financial stability. they are usually the bottom ranking people at the army and most of them wont make it to officer level their whole life time.
theres another class of people who do it entirely for prestige. in this case, people with army background in family, army connection and high school graduates who plan to make it through the ranks to become COAS. for instance General Gaurab SJB Rana, who is the next COAS after Chhatraman Gurung. Rana is the richest person in the army since he is "panati" of chandra sumsher and his sole purpose to serve in the army is for prestige and power.
you will start as leuitnent around Rs. 14,000 per month in the army even if you have pilot license. its very tough to get in and might require some connection in the army. the job brings you a lot of prestige, respect and power. army send their pilots frequently to the US for training and its all paid for. army job is not for you, if you looking to be rich but you can build some good hours flying and be financially stable. if you can get it, its good. good luck.
heres the salary structure
