A system may include a tactical military network including tactical nodes and a tactical gateway node configured as a trusted network access node (TNAN) to a mobile core network. The system may further include a military trusted interworking function (M-TIF) device of the mobile core network. The M-TIF device may support an interworking function between the tactical military network and the mobile core network. The M-TIF device may be communicatively coupled to the tactical gateway node. The tactical gateway node may be collocated with the M-TIF device. Services of the mobile core network may be accessible to the tactical nodes via the tactical gateway node and the M-TIF device.
