I think illumination shells...and maybe the other is a star cluster. I don’t think they are smoke rounds - you don’t use them at night. Certainly no WP. The Gaza hospitals would be full of civilian burn victims. I don’t KNOW what WP looks like, since we don’t use it anymore. In fact, I have never heard of a modern round specifically for fire bombing...but I’m thinking it would be a heavy shell set for groundburst....not delicately hang in the air and flicker.
I am with you. The ‘hang in the air and flicker’ has got me fooled.
And the use of WP in civilian areas would be a Reuters-ready moment.
Still baffled and ready to be educated.
