You just need to keep in mind one thing. You have 3 majors kinds of cluster ammo :
- the M77, BLU 3, tennis bomb or golf bomb have the size of a 40mm (+/-) grenade and detonate on contact. The major drawback of this desin it's the lake of terminal aiming. So the ammo ares just realase and dispersed one a wide area. Some hit de ground and act as anti personale frag grenade (the heat jet is wasted in the soil), other on the side or various angles. On the final only few sudmunition hit an hard target verticaly on a weak spot.
Another thing some munition could be detonate/disable/deviate in air by shrapnel/shockwave of close exploding ammo.
- BLU 108, Bonus shell submunition incorporate some detector (mainly IR) to track specifique target. This systeme use EFP (Explosively Forged Penetrator) and detonate at an average altitude/distance of 200m (600 ft) from the target. In this case you could see an airburst with a king of lighting under the smoke (the fast traveling projectile). It's more accurate, more powerfull (bigger diameter) but you have less sub munition (2 for the 155 mm Bonus shell vs 64 for the old M77 155m cargo shel).
- the third are the mines but it's another unit for WSPMBT

I hope it's could help you to have a better wiew of you videos or pictures.
