Hello,
I thought the thing with ammo was to represent the infantry being figural with ammo, which doesn't apply to OS
It is an abstraction that not only covers an average amount of effective damage per trooper vs. battlefield armor, but also the fact that infantry must spend some of their time reloading while moving under fire. Weapons with low shots per magazine require more frequent reloads, and heavier support-grade weapons often take more time because fewer members of the platoon are likely carrying as much extra ammo for those weapons as they are for the main weapons.
Note that Tactical Operations does have a Disposable Weapons rule that employs the one-shot weapons, enabling infantry to make one attack with their one-shot disposable weapons in place of a standard attack. We are presently working up an errata that multiplies the standard Disposable Weapon attack by 3 times the weapon's listed TechManual value to account for the specific nature of these one-shot weapons as non-reloadable weapons. (Thus, the LAW, listed as a 0.23 damage weapon in TechManual, would be calculated as a 0.69 damage weapon when used for a Disposable Weapon attack, but would only get to do so once per platoon/battle armor squad per scenario.)
Otherwise, expect no further "buffing" for conventional infantry.
Thank you,
