How many boomers should be allowed per person.

[Soothsayer]

I like the concept of limiting the max number of detpack explosive (whether the types we saw was a boomer or C4) based on the depth of specialization.

I'm still under the impression that C4 and boomer are two different things.

As a soldier generally, I'd say you should initially (without specialization into general soldier trees) be able to hold a small number of explosives, not enough to destroy a tank. With specialization into loadout efficiency or what have you the soldier would be able to carry additional C4, up to amounts that are in excess of what you would need to take out a tank.

Boomers on the other hand should be way more potent and limited to combat engineers.
