Helldivers 2 Ammo Economy: Resupply Is a Stratagem

Where ammunition comes from

The resupply stratagem, which drops a shared resupply point. It is the main source, it has a cooldown, and it is the single most under-called stratagem in the game. Support weapon resupply. Support weapons carry their own ammunition and often need a dedicated resupply call or a supply pack to be sustainable. Found ammunition. Scattered in the world, which is a reason to check containers rather than walk past them.

The timing rule

Call resupply before the fight that needs it, not after. A resupply called during a horde fight usually lands in ground you cannot reach, or it lands and nobody can break contact to use it. The habit: call it when the squad is at 60%, and treat the cooldown as the real constraint. On a long mission you get a limited number of calls, so each one has to land where the squad will be standing.

Conservation without being passive

The distinction that matters is what deserves ammunition, not how much you fire. Against Minoris, let sentries and area stratagems do the work. Against Majoris and armour, spend freely — that is what the ammunition is for. A squad that fires a hundred rounds at the chaff and then meets a Hulk with empty magazines has misallocated, not overfired. The squad roles page covers why this is a division of labour: the anti-armour player conserving rockets while the chaff player burns rifle ammunition is the system working correctly.

The supply pack question

A supply pack trades a stratagem slot for sustainability. That is worth it on missions with long approaches and heavy contact, and less worth it on short missions where one resupply covers everything. The trade is the same one the stratagem loadout page covers: four slots, four jobs, and resupply is one of them whether you budget for it or not.

The tell

If your squad keeps losing to the third or fourth heavy push rather than the first, ammunition is the usual cause. The difficulty page explains how the pressure scales, and the support weapon page covers which weapons are self-sufficient.
