I don't disagree with you that it's not cost effective. But the
Apaches are generally tasked to do all these jobs of wiping out
tanks, IFVs and also infantry troops. If it's cost effective to be
in charge of only tanks and IFVs, then why are they armed with
rockets and machine guns.
If mindef are really for really cost-effective heli, then they
should continue using AS-550 fennec, whereby they can carry heavier
load compared to EC-120.
