It's not a show per se. More complicated. But it is true that old units are being reclassed as commando units. Most of our active commando brigades are not actually "commandos"; they are light(er) infantry. No more motorized infantry in the ranks, they're all commando now. With 8x8 and tank deliveries starting, expect some of these commando units being reverted to mechanized units. Don't expect a large increase in manpower; it's more so a shuffling of the units; not increasing number.Our politicians can easily decide to increase troops counts, but that is probably because they can't deliver on hardware that TSK really needs. So they make a show of increasing troops.
But not to say that these lightly armed(less guns, armor) units have not worked good for us. For the kind of warfare we did in the last decade mostly in Syria, these highly mobile, easy to deploy units were more than enough for what we needed them for, and cheap too.
