Kilo Squad faced several Tickers inside the Museum of Military Glory's vaults and halls, normally summoned by Kantus monks, several of them tried to destroy Nassar Embry's armor along with a massive horde of Locust. Due to the gas released by tickers when about to explode, and the tanks mounted on their backs, it would seem that Imulsion is used to cause the explosions. They are quick moving and relatively difficult to detect despite the sounds they emit, making them dangerous and unpredictable adversaries, especially in large groups. However, the Locust use them against COG ground troops as well an example of this being the Kantus, which summon them two at a time and use them as a last defense when under direct threat by COG units. Tickers are always seen in large numbers, and are used mainly as mines against COG vehicles. They are small creatures that somewhat resemble a cross between a rodent and a reptile. They were named after the ticking sound they make while scurrying across the battlefield. Tickers were creatures found in the Hollow that the Locust used as a mobile land mine by strapping Imulsion tanks to them. Locust use them like landmines, so keep your distance.' - Benjamin Carmine and Tai Kaliso discussing Tickers
