Counter offensive has just started , reinforcements haven't reached the front yet..... patience is the key ... verily houthis goose is cooked.... major offensive will start from the East , end goal is not taiz it's Sana.
The govt doesn't have the manpower for Sanaa unless it retakes the sunni population centers controlled by the Houthi rebels to raise forces from.
Since the war began, The Yemeni govt has fought for strategic areas, marib's oil and western coast, and half heartedly tried to defend the population centers. That has come to bite them.
The best case scenario for them that they MIGHT be able to achieve is
hold bab Al mandab, maybe extend until mocha, and then destroy the
pincers around taiz. Dreams of Sanaa are delusional unless they have a hidden army hiding in the desert no one knows of.
Even the things I mentioned I am not 100% certain the can achieve.
The Yemeni army for years have been sitting on it's ass instead of modernizing. There are some drone units and the footage of drone drop munitions have jumped up significantly but clearly limited to few brigades like the giants, instead of the entire army.
They have failed to combat rebel numerical superiority with technological one.
They bank on Saudi airforce but targeting a moving rebel army in close quarters to Yemeni army, with no distinguishing features that can be spotted from the air, the Saudi airforce can only target fixed position which there aren't many especially on a moving front.
Anyway, the one that adapts faster will win.
