when i was in NS, got a platoon mate got his shin hit by a sledge hammer, and somehow he never got downgraded and he kept failin his IPPT because of that. he only got downgraded when he was abt to ORD. So breaking a leg may not get u wat u want...
Got another platoon mate who was downgraded becasuse of back injury, and then 6months before he ORD, he got upgraded and have to go for vocation training course ...so if u want to downgrade make sure its permanent
