Are you allowed to take units?

Unit? is that a chess term? Can I assume you are talking about a chess position?

If we are talking about chess, it would have to be after a number of takes. I don't think you can even set up a position with all 32 pieces on a chessboard where no piece attacks or defends another.

the key problem with leaving all of the pieces on the board is that the queens + bishops + rooks all have long attacking capabilities, so i agree that it shuld be impossible with all pieces on the board

Yes. I believe you must take at least 4 units (even if you don't try to find the shortest game), i. e. in a position with no attacks or guards the number of units is at least 28. But that's another puzzle (find a legal position with 28 units without guards or attacks).

Of course, you are allowed to take more than 4 units.

Officer = K, Q, R, B, N
Piece = Sometimes means K, Q, R, B, N, sometimes means also P
Man, Unit = K, Q, R, B, N, P

I wanted to include all 6 types (K, Q, R, B, N, P) so I said "unit" and not "piece".

The shortest game in which all pieces are captured could function as a starting point.

Are the rules of a normal game in place, i.e. check/checkmate on the king?

This is not minimal. This is the first attempt by me or indeed by anyone, and gives you a nice number to beat:

1. b4 g5 2. Bb2 b5 3. Bxh8 Bg7 4. g4 Bxa1 5. Bxa1 Bb7 6. f4 Bxh1 7. Bg2 e6 8.
Bxa8 Bxa8 9. d4 f5 10. e4 fxe4 11. d5 e3 12. dxe6 dxe6 13. Qxd8+ Kxd8 14.
fxg5 Ke8

I have always heard the following terms associated with this definitions.

Unit - Any chess piece, including pawns.
Man - Any chess piece other than a pawn.
Major Piece - Queens and Rooks
Minor Piece - Knights and Bishops
Royalty - Kings and possibly Queens
Piece - Either Unit or Man, depending on whether pawns count (I can't recall)

I was told the Pawns were not Pieces.

Typical elitist snobbery! That's just the tall man trying to keep them down.

why is everyone bickering about such a trivial matter? as long as we all understand what the OP had in mind it doesn't really matter
