Ack 

Short for “Acknowledged.” Mostly used by military personnel to quickly confirm that they received the sender’s note, email, task, order or request.

“Ack” can also mean “Yes; Ok; Got it; I’m on it; or Confirmed.”

Cpl Smith,

Please follow up with the Chief Engineer to make sure he has everything he requested from our team.
