Strategies:-
A new breakthrough in technology allowed Flak-Rigs to have the BOTH the abilities to bombard Air and Ground forces. The Trebuchet was thus made. The Trebuchet's main artillery component consists of 3 elements. 1) Sensor 2) Ground Firing Cannon 3) Air Firing Cannon. The sensors provide range for the Trebuchet so that it can arb/ball properly. The Ground Firing Cannon lets it have the ability to Arb ground units just like an Arbalest while a Air Firing Cannon allows it to have the ability to Ball air units just like a Ballista.

V-Artillery:-
For a Trebuchet to switch between Ground and Air Firing cannons, it must first updeploy, switch to the desired cannon and then deploy again. The damage for the Trebuchet isn't really great because it is versatile but it helps in situations where you need BOTH arbs and balls but have none. Although the Trebuchet can hit both air and land, it still has the same weakness just like any other artillery unit: Melee Units. Melee or close range units or cloaked, camoed units can easily avoid the shells fired from the Trebuchet. However, the Trebuchet can walk considerably faster than an arb or ball thus, this is their only advantage when it comes to close combat.
