Suggest you let your friends at that defense foundation keep on at the tom foolery going on inthe OFB, they have the will, patience and the fortitude to discuss. We fall far short here, as you can see.
Found another 'gem'
IOFB wants to make a 3 cal, interchangeable , bull pup design because:
5.56mm- conventional warfare, wound your enemy, let the REMF types get busy handling the casualty-ties up the infrastructure
7.62-heavy bullet for the terrs/tangos-because they are hopped on on joyjuice/religion/ brainwashed-keep fighting/spraying bullets till brain dead-therefore heavier cal required-the five seven FN used by the SPG is ONLY used to shoot 'miniaturised' threats- snow white and her pals are now in danger, what?

6.8 for spec ops-like any group/force which is tasked by the SF, suddenly grow kevlar breast/trauma plates with letters of flaming gold, 'SHOOT HERE WITH 6.8 ONLY ' 30 min ago, they were being taken out with 7.62 AK, SLR,and/or INSAS-by the normal Police/ Fauji's, whatever
They just re wrote the doctrine of warfare here!
Bolstered with the confidence of the iffy functioning of their flagship INSAS (didnt the nepali's reject the INSAS a while ago?) comes the confidence to try a moon shot.
IMO-take ONE technology, perfect it, and make it a world beater, instead of 3rd rate bedpan mechanics building 4th grade systems, endangering millions of our FIRST GRADE JAWANS.
