LEN formula - if string less than 3 cut off last letter

[Ace71425]

I'm looking for a formula that takes the string in A1 and if the text is 4 or greater characters I want it to display the first 3...if the text is 3 letters long I want it to display the first 2...if the text is 2 letters long I want it to display only the first character....let me know what that formula would be I'm assuming using left and len. Thanks!

That is odd because that is not what happens on my samples. I even tested Rick's formulas from #5 and it does the same as mine.
