The basic hull of the M8 is made of welded aluminum alloy, with a unique modular armoring system that allows the vehicle to be equipped according to requirements. The Level I (basic) armor package is designed for the rapid deployment role and can be airdropped from a C-130 Hercules and protects the vehicle against small-arms fire and shell splinters. The Level II armor package can still be carried by C-130, but must be airlanded and is designed for use by light forces in a more serious threat environment, while level III armor is designed for contingency operations and is supposed to provide protection against light handheld anti-tank weapons. Level III armor cannot be carried by C-130. All versions are air-transportable by C-5 Galaxy and C-17 Globemaster III (five and three respectively).
The M8 is armed with the M35 rifled autoloading 105 mm cannon main gun with an M240 7.62 mm machine-gun mounted co-axially. The M35 has a rate of fire of approximately 12 rounds per minute, with a ready capacity of 21 rounds with 9 more in stowage. Power is provided by a Detroit Diesel 6V-92TIA diesel developing 580 hp.
