All T1 mobile artillery have the characteristics of a high firing angle, giving them the ability to shoot over obstacles otherwise known as indirect fire. They also have great DPS for their mass cost, and are therefore still useful in some circumstances late in the game. Early on, they are employed largely to destroy T1 point defenses due to their long ranges, and can, if ordered to attack a point just next to the point defense, usually destroy them without even getting into their range.
UEF Lobo: Has the highest HP and reload time of all the other factions' equivalents. Also is equipped with shell cam, or line of sight of the detonation area. Shells split into 5 smaller ones, much like the Seraphim Zthuee. Slower than the Cybran Medusa but faster than the Aeon Fervor and the Seraphim Zthuee.
Cybran Medusa: Has the lowest HP and second slowest reload time of all four factions equivalents. Has the lowest DPS, but its shell has EMP, or stuns its targets. Its stun ability makes it still useful late into the game, to paralyse enemy units. Has the second highest mass cost, highest energy cost and build time, but moves faster than the all the other equivalents.
Aeon Fervor: Has only 10 more HP than the Medusa, but boasts the highest DPS and rate of fire. It is also the cheapest T1 mobile artillery in terms of mass(along with the Lobo). Despite these advantages, the Fervor is cursed with a very small projectile damage radius of 0.5,the smallest and rendering it somewhat less useful against mobile targets and best used against structures or slow-moving units.
Seraphim Zthuee: Has the second highest HP but with the highest mass cost of the four mobile artilleries, being more expensive than the Aurora and Mantis, 2 mass cheaper than the MA12 Striker, and equivalent costs with the Thaam. Despite this, the Zthuee is arguably the most effective T1 mobile artillery for several reasons: it hovers, it has good damage and it has Lobo's area of effect. It has earned the nickname "Fobo" from Aeon Fervor and UEF Lobo because it combined UEF's projectile (also splits and also high AOE) and Aeon rate of fire (Fervor has the highest ROF).
