Tenacity and arsenal 2

[EvincarPresto]

If i have arsenal 2 and are engaged with two different units while wounded and equipped with tenacity, do i get to add a red dice to both pools if i split my attacks?  Or do i have to choose which pool will get the red dice?

Hi there,

A unit with Tenacity may add a red attack die to any and all of its eligible attack pools, as it forms them.

Hope this helps,
Seth
