Keep in mind that ammo is precious, though. It's far from uncommon to have Mech duels fall to energy weapons or even melee combat in the end, the Mechs in question being tough enough or numerous enough to outlast the missile and ballistic ammo supplies available to their enemies. And we're at a disadvantage in this sim because the OpFor has a bunch of disposable vehicles to soak up our ammunition and wear us down with attrition before their Mechs hit the field.
