I tot of that too.
All airborne troops dun have to be all foot soldlier.
They could be operating the air-droppable armoured asset like the
Russian BMD-1,BMD-3 or the German Wiesel.
Now there is one NSF bn, and a NS Bn which is still within 1-6
ICTs, the older NS Bn which will be fully converted to a fully
airborne armour Bn say in 6-10 ICTs.
Let's say is a fully Wiesel Bn, armed with 20mm cannon, Spike ,SAM
variant of the Wiesel 1/2 AFV. For more firepower , maybe even with
M8 Thunderbolt.
Therefore , this Bn will be less strenuous as they will air drop
w/o fullpack, all their the rest of equipment will be in the
air-dropped veh. And they will fight in their veh , supporting the
fitter two Bn.
So in way still fully utilised combat fit commando(28-33 y.o.) in a
less strenuous role & at the same time give the strike trooper
more firepower.
