Here is his Wikipedia article.
Aloni has been behind many of the war crimes and air strikes in Gaza and the Gaza Strip, and he is also a head advisor to the IDF for military incursions into Palestinian territory.
Aloni was also the architect and general behind Israel’s 2021 “Operation: Guardian of the Walls”, which killed and wounded an estimated 4,000-5,000 Palestinians, and displaced 72,000+ Palestinian civilians.
The Depth Corps is a unit specialising in operations against Hamas, Hezbollah, and Palestinian Islamic Jihad. They were behind many of the Mosque bombings, forced evictions, air strikes, and terror attacks on Palestinian civilians over the past two decades. The unit is currently in shambles and is being reformed behind the lines.
His attire is pretty standard military sleepwear, and especially due to his lack of shoes I don’t think they stripped him down, but legitimately caught him sleeping.
Also barracks are only for enlisted soldiers and low ranking officers. A flag officer like a Major General would have special and designated housing on-base in the form of a house, or suite, making finding him extremely easy.
They will also not give him up without some major concessions. Hamas will probably use him as a human shield and bargaining chip to help prevent retaliation against civilians. Then they can exchange him at a later date.
Worst case scenario, his execution would be an insane propaganda victory.
