Both sides hide casualties or significantly delay disclosures. A simple case in point, on average Indian Army is incurring 280 military casualties each year along the LoC/IB. Despite that, the reporting in Indian press is for no more than 20% of these casualties.
Let's not be so gullible about this and believe whatever the governments put out on both sides as the benevolent truth.
Not in india , not in India 2018 .
Every military , even paramilitary causality BSF at the loc is media event in india and reported by media and Army's @adgp twitter handle and also not just that local and national tv telecast their last rites and families are interviewed . Opposition parties too keep a close eye on it . Even questions are asked in parliament and govt has to give figures and can't avoid like they do in pakistan when PA refused to disclose casualty figures to your Senate members .
PS: What you are saying is probably true for at the time of war .
