Not 100% sure from the vague description given, but when firing at infantry or other soft targets you sometimes do not get the full "chain of fire" if:

- The infantry pull back due to fire weight and/or casualties. Regardless if they pop smoke when doing so.
- The infantry/crew take cover, hit the dirt etc.

This includes any other infantry (whether spotted or not) in the target and other impact hexes (from weapon scatter when the "sparkler" goes off in an adjacent hex, or blast radius if the weapon has blast effect).

These target reactions break the "chain of fire" of the firing element, and it does not have to be the targeted enemy element that triggers the break. Just one affected by the firing.

Typically you may see this effect when spraying a bunch of infantry elements with a MMG/HMG team with multiple MGs in the firing element. Your firing may stop say after the first weapon fired - if watching the target you may have noticed an element pull back, but if it was an unspotted enemy that ducked and dived, perhaps not.

The other reason fr perceived gaps in firing is that the weapons dont have any ammo in one slot or the other - weapons further down the list may have more ammo left, since effects of the above mean the previous ones expended more rounds. Also, if weapon #2 killed a target, then weapons #3 and #4 do not fire at the killed target, thus leaving more rounds available in those slots. So check your ammo - some slots may be at 0 and the others at >0.
