This is the application of the 50/50TACDOC to Highrise.  The first thing to do is identify the Key Avenues of Approach (KAA).  As per the doctrine the KAA will be marked in black while the Secondary Avenues of Approach (SAA) will be marked in Teal.  The OPFOR spawn on this map is not marked correctly so I have drawn in my own marking.

Now that the KAA have been identified it is time to designate three Areas of Responsibility (ARs).

The three ARs have been designated AR Elevator, AR Middle, and AR Helipad.  Because all three AR are long and narrow on this map it makes sense that the AR owners should be snipers or other long range builds.  Long range builds are recommended for each AR but there are enough nooks and crannies that a camping shorter range build could do the job.  Remember, I don’t care how each man takes care of his AR so long as it is taken care of.

The major vulnerability that is not addressed by the three ARs is the Red Pit tunnel.

This is marked as a SAA but anyone who takes that route could get behind all of the AR owners if they are sniping from the building.  This weakness can be mitigated by using claymores or having the Quick Reaction Force (QRF) or the Mobile Forces (MFs) covering the tunnel.  The QRF is not a very reliable defense because the QRF will probably be called out to help one of the AR owners.  As we all know, claymores are a decent defense but they can be circumvented.  This means that it falls to everyone to keep a loose eye on that area and if the MFs want to cover that area then more power to them.

Provision to the 50/50TACDOC for Highrise or any other map:

If any AR owner is getting taken out regularly they can request that someone take their area from them.  The AR owner must watch their area until someone relieves them and then the AR owner must assume the duties of the person replacing them.  The same goes for anyone that wants to change their duty position for any reason.  If a MF wants to take an AR position he must have an AR owner agree and then go relieve the AR owner.  Changing positions is a two way street.  If the QRF wants to switch role he must wait for the person to relieve him as well.  This way is someone is having a bad game in any role they can change roles.
