Military vehicle
A military vehicle includes a passenger capsule having a front end and a rear end, a front module coupled to the front end, and a rear module coupled to the rear end. The front module includes a front axle, a front differential, an engine, and a transmission. The front differential is coupled to the front axle. The front differential functions as a structural component of the front module. The front differential defines an engine mount. The engine is at least partially supported by the engine mount of the front differential. The transmission is coupled to the engine. The rear module includes a rear axle and a transaxle. The transaxle includes a housing, a transfercase disposed within the housing, and a rear differential disposed within the housing. The transfercase is coupled to the transmission, the front differential, and the rear differential. The rear differential is coupled to the rear axle.

6. The military vehicle of claim 5 , wherein the front differential is a front structural component of the front module, and wherein a housing of the transaxle is a rear structural component of the rear module.
7. The military vehicle of claim 6 , wherein the front differential defines an engine mount to which the engine is mounted.
8. The military vehicle of claim 6 , further comprising a suspension system, wherein a component of the suspension system is directly coupled to a housing of the transaxle.
9. The military vehicle of claim 8 , wherein the component includes at least one of an upper control arm, a lower control arm, a spring, or a damper.
10. The military vehicle of claim 5 , wherein the passenger capsule has a monocoque hull structure that does not include frame rails extending along a bottom thereof.
11. A military vehicle comprising:
a passenger capsule having a front end and a rear end; and
a front module coupled to the front end of the passenger capsule, the front module including:
a front axle;
a front differential coupled to the front axle, the front differential functioning as a structural component of the front module, the front differential defining an engine mount; and
an engine at least partially supported by the engine mount of the front differential.
12. The military vehicle of claim 11 , wherein the passenger capsule has a monocoque hull structure that does not include frame rails extending along a bottom thereof.
13. The military vehicle of claim 11 , further comprising a rear module coupled to the rear end of the passenger capsule, the rear module including:
a rear axle; and
