Mostly from an old tanker's view.
The conflict in Ukraine has led to many innovations; so much that the face of war as we have known it is changing rapidly, moving in a rapid flux..
Foremost in visibility perhaps, is how a weapon costing a few thousands of dollars, can eliminate a weapon costing millions.
Recently a Ukrainian done is credited with bringing down an advanced Russian bomber worth $ 100,000,00, while the same drones are killing tanks which range from 5 to 10 million dollars apiece.
Drones are changing much of the face of warfare even now, witnessed by action in the Ukraine.
Obviously, armored warfare is to undergo a revision. The medium and heavy tanks are likely to phase out, in favor of lighter, more nimble versions.
While physics at present, won't allow large, conventional guns to operate efficently on a light chassis, new missile type ordnance is developing apace.
One vulnerable point on a coinventional tank, is the turret ring, the geared ring which the turret turns and permits accurate firing. Drones are seen specifically targeting that ring. If that ring is just jammed, say nothing about penetrated, it would require aiming the gun tube by turning the entire tank. That is too slow to reply and live...and not likely to be able to draw a fine zero on any opposing source of danger.
Coming soon, crewless weaponry. I can visualize such a light tank, with armor protecting the essential vitals..with no need to protect the creeew or worry about crew comfort.
New, composite and reactive armor makes lighter carriers more feasible, no turret required, since the missiles replacing the gun tube, can redirect their flight in the air. Robots in place of crewmen would solve an long held problem of armor designers..the height factor.
In any combat situation, a low profile is desired, reducing the target area. We tankers went through training with some fellow trainees who wer 6'5"
tall or more..we viewed that as just more Army SNAFU. A man that tall has difficulty when in a tank turret for any extended period.. and crew
comfort is more critical than many realize.. Travelling for hours cramped up, may hav esome suffering from fatigue when they arrive at a point of action.
Today's slogans may change.....armor used to be "the combat arm of decision"..will it remain so ? I have confidence that the infantry will remain "the queen of battle", simply because, like the queen in chess...it is infantry that holds the ground once captured.
Drones and AI will greatly alter the battlefield of the future.. even taking it to fields of battle yet unheard of..the reason for our new Space Force.
