Bots are highly maneuverable legged units designed to outmaneuver their slower tank based counterparts. Bots are as a rule less heavily armored than Tanks of the same Tech level, but with effective micromanagement can bring down the tanks with minimal trouble. The Cybran Hoplite and UEF Mongoose are examples of units which excel when managed well. Tech 3 ground units are generally Bots, as well as some Tech 1 units. Bots are fast, and agile units great for scouting and raids. Heavier bots like the Percival and Brick are slower than most other bots but they are much more powerful.
The mantis spam Edit
One thing cybran players like to utilize is the mantis spam. This is different than t1 tank spam because mantis, as an assault bot, is cheaper and builds faster, but does less damage and is weaker. Mantis spams are preferred by players because of the cheapness and speed of which they can be produced. When paired with a mole, they can make excellent mex killers. One other advantage is their speed. It is slightly faster than other tanks making flanking and getting behind tanks and bases easier. However, late game they are even more useless than t1 tanks due to their lower health and damage. late game, It doesn't matter how many mantis you have. The spam just can't compete with t3 and experimental.
The Tech 1 light assault bots, the UEF Mech Marine, the Cybran Hunter, and the Aeon Flare, have a unique ability: They are the only Bots, or land units in general, able to fire their weapons while on a transport. Players have exploited this technique to create a makeshift air-to-ground aircraft, dubbed the "Ghetto Gunship". Although LABs are weak, and as such don't find much use on the battlefield, they can severely damage an army when fully loaded into a transport and survive to do enough damage, as opposed to lasting just briefly in a firefight. The UEF have a significant advantage in this, as their T2 Gunship, the Stinger, has a single transport hook. Since that one hook wouldn't have much use in transporting, as you would probably need that gunship for its combat role, why not give it an extra 21 DPS?
The UEF also have a Heavy Air Transport, which conveniently has shields and Air-to-Ground weapons to begin with, so your LABs will be protected.
