The Driller APC (Armored Personnel Carrier) is Epsilon's primary infantry transport, which moves underground, allowing it to bypass terrain obstacles or enemy strongpoints and take Epsilon infantry for surprise attacks.
Drillers are Epsilon's primary armored personnel carriers, with a twist. The Driller is equipped with a large, tungsten-coated titanium drill on the front, allowing it to quickly tunnel into the earth and avoid enemies and terrain obstacles altogether. Though this gives the Driller the ultimate element of surprise, it can only carry up to three passengers and is completely unarmed. The Driller's armor, though strong enough to withstand the dangers of subterranean travel, offers little resistance to enemy fire.
Each Driller can transport up to three infantry units, higher than Halftracks and equal to Tigr APCs but lower than Stallion Transports and Borillos/Armadillos. The Driller, however, can travel underground and bypass natural obstacles such as mountains and cliffs, providing a better flexibility for Epsilon forces.
A common tactic used by Epsilon proselytes was to load up a Driller with Engineers (sometimes accompanied by escorts for diversions), burrow into the base and come out next to an important enemy structure (preferably a Construction Yard) and quickly capture (and sell or use) them before the enemy could respond. The same tactic can also be used to quickly capture tech buildings behind enemy lines and safely transport Infiltrators to the enemy base.
However, the Driller cannot burrow in or out of the ground if the area was either shrouded or had uneven terrain. Burrowing in or out an ore/gem field will cause the ore/gem at where the Driller burrows in or out to disappear as well.

|—Epsilon intel during Operation: Focus Shift|
- In Beautiful Mind, after the MIDAS strike happens, a red Driller appears, sending out Desolators. These forces belong to Yuri, as implied later on in the Act Two mission Firewalking.
- In Singularity, after all designated targets are destroyed, Malver, the Virus and the PsiCorps Trooper must reach a Driller to be evacuated.
- In Moonlight, once a Rocket Launch Bay is captured, a Driller will arrive to extract its contents, and both must be protected until the extraction is completed.
- Driller becomes first controllable and buildable in Memory Dealer.
- In Divergence, three minutes after the old Chronosphere is captured, four Drillers will arrive to dismantle it, and they must be protected for three more minutes.
- The Driller is unavailable to the Epsilon forces in Withershins, Hamartia and Babel, as the ground is too tough for subterranean units to dig through.
- In Death's Hand, Yuri will evacuate through a Driller after the Kremlin is destroyed. However, he will resurface in one of many possible locations in the map, allowing the Soviets to finish him off once and for all.
- In Survivors, when a Neurotoxin Vats is captured, a Driller will arrive to extract the neurotoxin; if either is destroyed prematurely, the extraction fails. Seven of the 13 vats present must be captured and extracted this way.
- In Dawnbreaker, minutes after protected Palace and gained an MCV, a Driller will be seen that unloaded several Epsilon infantry and then defected to the Soviets, becoming controllable by the player.
- Several Drillers can also be seen as PsiCorps enemy units in Enforcers, but the Allies believe the enemy are Russians.
- The Driller is based on the from .
