The British Army tested the transport version of Titan for front-line logistics last year. The Last Mile Resupply Challenge was carried out at Salisbury and seeing how easily robots could bring ammunition right to the front line.
Rather than cargo though, THeMIS can use its 750-kilo carrying capacity for a weapons turret.
Several different versions are available with turrets from a variety of international manufacturers reflecting how many countries have taken an interest. These offer various weapon combinations, including 7.62mm medium machine guns and .50 heavy machine guns as well as guided anti-tank weapons such as the Javelin missile.
Titan is not seen as just a stand-alone system - one of its strengths is the ability to work in co-operation with other unmanned systems.
In Commando Warrior, the robots were used alongside small reconnaissance drones, used to locate targets. Mr Väärsi says that in future they hope to have a seamless hand-off, so the operator can get a target in the crosshairs of a drone, and the ground robot will automatically rotate its turret to aim at the exact spot indicated.
Going forward, such robots will become integrated more closely into the squad. The goal is to have them controlled more like another human than a robot, able to respond to voice commands and gestures.
For example, being able to give a ‘follow me’ order is far simpler than having to program a route in advance.
Other nations are also experimenting with their own armed ground robots. Russia in particular has taken an interest in moving UGVs to the front line, and deployed a number of armed Uran-9 unmanned vehicles in action in Syria last year.
These apparently performed poorly, largely due to issues with the radio communications. The makers say they have learned from this and that all the identified problems have been fixed, and the Russian army is set to received production vehicles this year.
Exercises like Commando Warrior should identify any problems with Titan before it goes into action. In the exercise, the Royal Marines landed covertly on the beach, climbed cliffs, assaulted an ‘enemy’ position with fire support from the UGVs, and withdrew safely.
Commando Warrior explores how the Future Commando Force might operate by taking advantage of the latest technology and integrating robots into fighting units is still a distant prospect.
It may still be some years before Marines have droids for fire support - but the day might be closer than you think.
