VComm and V+ supports HLA; in fact they support DIS and HLA both. DIS is provided by default in PN: VCOMM-X86, while HLA capability is provided by this separate extension software. This software add-on to VComm, adds the functionality to VComm to utilize the MAK 1.3 RTI. When installed, this add-on also installs the MAK RTI (the MAK RTI is purchased by the User separately through Mak Technologies). See the VComm User Manual for more information.
