The internal communication of the car today does not simply unite the crew into a voice network with the aim of obtaining legible voice communication between crew members when the platform moves on the battlefield. This need remains today, but the digitization process does not stop at the machine, the crew members are also required to send and receive data necessary both for the operation of the machines and for the expansion of situational awareness.
Cobham's ROVIS / VIC-3 intercom system has over 120000 users in more than 25 countries, including the United States, where it is the standard intercom system for military vehicles. A number of modules have been developed that can be integrated according to the platform’s functions, right down to the mobile command post. The system allows you to interconnect up to six radio stations, users can choose the desired radio station that they want to use from any crew location throughout the vehicle in accordance with access plans, which can be set up for each painful task separately. Internal communication is also built around such a structure, which allows two channels for voice / data and power supply, thus creating greater redundancy, since both elements can be automatically redirected.
For machines with a limited internal volume, Cobham has developed LV2 with a simpler setup, it has a high level of redundancy due to the minimum installation of the Master Control Station Light and one or two full-function crew terminals. All LV2 modules can interface with other ROVIS / VIC-3 systems.
In order to ensure future compatibility with additional protocols, such as IPv6, Cobham developed TACG2. A feature of the systems is that the modules can be integrated into existing networks of RIOVIS / VIC03 machines, and can also be used to integrate the capabilities of IPv6 into existing systems.
The modular units that make up the TACG2 system are similar in form and function to existing control units, which eliminates the need to drill new holes in the body and the tower of the machine to install them. New additional elements are remote control of combat network radio stations from the crew members' places, conference communication, point-to-point communication for reports between crew members and the introduction of individual communication system settings for crew members.
Cobham has recently begun work on the delivery of the VIS-X system, which will initially complement and then finally replace VIC-3. For the VIC-3 product, Cobham collaborated with Northrop Grumman and delivered the systems through Northrop Grumman Cobham Intercoms LLC under a contract worth 2,4 billion dollars; The first copy should be delivered at the end of the 2010 year.
Thales' SOTAS system is the main contender for Cobham, as Australia recently decided to replace existing ROVIS systems with SOTAS on BUSHRANGER machines.

EID’s ICC-201 digital intercom system installed on a number of Portuguese military vehicles
In contrast to a dismounted soldier, whose priorities are hearing protection from impulse noise generated by cannon fire or similar sources, hearing protection for car crews must deal with disorders that accumulate during prolonged exposure to noise generated by normal operation of the machine, especially engine noise and tracks. Obviously, the desire to preserve hearing has tactical advantages in combat operations, so the requirements to prevent damage to hearing organs, at least for EU countries, are supported by European directives on physical factors.
The PICVC system (Product Improved Combat Vehicle Crewman - a product that enhances the capabilities of the crew of a combat vehicle) from Bose is widely used in the US Army and is used as a standard solution for the M-1 ABRAMS tank, the BRADLEY BMP, the M109 PALADIN self-propelled howitzer and other tracked armored vehicles.

RA315 Helmset - “connection” of communication headset and helmet suitable for crew members of combat vehicles
Bose's main competitor in the hearing protection market for car crews is Esterline Racal Acoustics. The company's RA315 Integrated Helmet System is a further development of the RA180 Crewguard product, originally created for the British Army and optimized for the unique helmet design. The company took the main components of EA180 and refined them for installation on other, as a rule, more affordable headphones. Both head phones are used for heavy cars making more noise; when using passive and active noise cancellation, they can protect against noise up to 120 dB. These systems are used in a number of countries, including the UK, where these hearing protection systems for their car crews have been used since 2011. The company is considering its options for future projects, including modular systems that could include "in-the-ear" solutions - universal for a dismounted infantryman's systems - but with additional protective devices for the crew of each particular machine.
Esterline Racal also sold over-the-counter 80000 RAPTOR 25 headsets on the US market for use in MRAP and STRYKER machines. The new model RAPTOR was developed in the US branch of this company.
