Yes, and always.Well i do think Air Superiority is very vital in any large conflict, thus no amount of Air defense system'you are employed there Will be not much to cover the whole teather of operation 24 hour o'clock and defend the whole units. While Air Superiority would deter the enemies movement to large extend and instead focused their move around defense thus create the opportunity for the adversary to break the lines by Exploit any weaknesses arise.
But in case of my comment is representing what Ukr have right now. They only have Arty in numbers that can hit Beyond Visual.
If one of the opposing front already secure the air I think the conflict will only last Weeks. But hence have so much Jet and bomber in paper, still failing to gain Air superiority.
Thats why in situation which is more fatal than Ukr securing Air and sea is a must, alas none politician bats an eye.
I mean, WTF dude why every one believe peace will last forever. become less aware with situation coz never have a rival thus make this country never afraid with war.
But, the most iritating stuff is this nation never has medium term plan. Every purchase always from Politics ego, one time ago a top notch want Black Hawk, the other want diverse fixed wing.
Dude cmon, use what you have right now, for example use H225 for al utilities helo, use F16 to do all stuff and spam them it can cover all you need. Damn, i just hope Indonesia have long term planning and budgeting, not every election create from scratch
