You didn't get my "it's luxury" point.

Compare your Vietnam IDs with foreign IDs and you'll see that their army aviation support is anywhere from non-existing to much smaller.

Sure, army Aviation can do much - it better should, for it's very expensive and thirsty - but you can do without. No LRS establishment needs to atrophy only because there aren't enough helicopters.


Besides; speeds are only meaningful in relation. The slowness of high altitude combat affects both friend and foe. This relative slowness in comparison to other operations is ceteris paribus not matched by relative slowness in comparison to the enemy and thus not relevant here.
