Narrative:
The local control #2 position and local control #3 position at las (las vegas tower) are being combined due to lack of staffing. The LC2 position controls aircraft landing the north south runways (runway 19L/right). The LC3 position controls the class B airspace assigned to the tower at las. The LC2 and LC3 position being combined contributed to a recent operational error where a citation was crossing the runway while an air carrier was departing the same runway. The 2 position are inherently different and should not be combined. The LC2 position is responsible for the runways (19L/right). The LC3 position is responsible for the airspace. The scans required for each position detract from one another. The controller working LC2 primary scan should be the runways; while the controller working LC3 has a primary scan on the radar scope and the B airspace. Combining these 2 position is dangerous and has already contributed; at least in part; to 1 operational error. The ability to combine like position at las tower is available and should be utilized.

Title: LAS TWR CTLR RPTS ON RECENT OE AND EXPRESSED CONCERN REGARDING FAC STAFFING THAT PROMPTS THE COMBINATION OF LC POS WITH VERY DIFFERENT RESPONSIBILITIES.
Narrative: THE LCL CTL #2 POS AND LCL CTL #3 POS AT LAS (LAS VEGAS TWR) ARE BEING COMBINED DUE TO LACK OF STAFFING. THE LC2 POS CTLS ACFT LNDG THE N S RWYS (RWY 19L/R). THE LC3 POS CTLS THE CLASS B AIRSPACE ASSIGNED TO THE TWR AT LAS. THE LC2 AND LC3 POS BEING COMBINED CONTRIBUTED TO A RECENT OPERROR WHERE A CITATION WAS XING THE RWY WHILE AN ACR WAS DEPARTING THE SAME RWY. THE 2 POS ARE INHERENTLY DIFFERENT AND SHOULD NOT BE COMBINED. THE LC2 POS IS RESPONSIBLE FOR THE RWYS (19L/R). THE LC3 POS IS RESPONSIBLE FOR THE AIRSPACE. THE SCANS REQUIRED FOR EACH POS DETRACT FROM ONE ANOTHER. THE CTLR WORKING LC2 PRIMARY SCAN SHOULD BE THE RWYS; WHILE THE CTLR WORKING LC3 HAS A PRIMARY SCAN ON THE RADAR SCOPE AND THE B AIRSPACE. COMBINING THESE 2 POS IS DANGEROUS AND HAS ALREADY CONTRIBUTED; AT LEAST IN PART; TO 1 OPERROR. THE ABILITY TO COMBINE LIKE POS AT LAS TWR IS AVAILABLE AND SHOULD BE UTILIZED.
