The command-observation post is intended for making reconnaissance, determination of coordinates to the targets and fire control. The command-observation post is situated in MTLB-U armored vehicle and is a fire control vehicle. The command-observation post is deployed at a distance of up to 1-3 km from the forward line. The data transmission channel is organized on the basis of W-LAN computer network between the command-observation post and the portable reconnaissance post, and WAN computer network between the command-observation post and the fire control post by using VHF radio transceivers with data transmission speed of 16 KB/sec.

The command-observation post consists of a fire control vehicle and up to 4 pcs portable reconnaissance and control posts. The fire control vehicle consists of:
- onboard computer;
-printing device;
-HF radio transceiver, only for the command vehicle of the battalion commander and batteries commanders;
-VHF radio transceivers – 3 (three) pcs;
-access device – for W-LAN setting up;
-hub (concentrator);
-laser range finder;
-sensors to measure the command vehicle tilt;
-remote control and laser range finder observation system;
-satellite navigation system (GPS);
-independent navigation system;
-artillery gyrocompass;
-life provisioning equipment etc.

Onboard computer.
The onboard computer is a basic component in ATABFCS “Vulcan-B” and is intended for:
-binding of all components in an integrated fire control system;
-display of the battle formation elements on a geographic information system;
-coordinates determination of the battle formation elements and the targets;
-fire data determination;
-exchanging information about the reconnaissance targets, fire data, commands, orders etc.
The onboard computer exchanges information with:
-the range finder, the sensors for measuring the command vehicle tilt and the remote control and laser range finder observation system by RS 232 cable interface;
-the radio transceivers through LAN network; forward reconnaissance and control posts through WLAN network.

VHF radio transceiver.
The VHF radio transceiver is intended for exchanging speech data and information through digital channel at 16 KB/sec. The VHF radio transceiver is an up-to-date contemporary transceiver having data transmission modem and encryption module. The VHF radio transceiver communicates with the onboard computer through LAN network. There are three radio transceivers in the fire control vehicle.

HF radio transceiver.
The HF radio transceiver is intended for exchanging speech data and information through digital channel at 3,6 KB/ sec. The HF radio transceiver is an up-to-date contemporary transceiver having data transmission modem and encryption module. The HF radio transceiver communicates with the onboard computer through LAN network. In each fire control vehicle there is one transceiver for the battalion commander and one for the batteries commanders.
The fire control post and the command-observation post are of one and the same type and completely interchangeable.
