tactics

Hi everyone. I am confused about the differences between strategy, operations and tactics. I think most people confused those words and that makes me confused as well. Can you define those terms?

Can anyone here post links for evaluations of the impact of active defense systems for vehicles on supporting infantry tactics? It seams to me that infantry would want ot stay well away from a vehicle that is likely to fire on them without warning!

post any military tactics THAT YOU THOUGHT OF!! post it here my new idea was to have 5 main brigades. 4 medium sized and 1 small that would be used to sneak a flank. its more of something that would be used during the civil war era but its not like how every other tactic is like one line...

can anyone help me Im looking for information on the history and evolution of military tactics and strategies
