A figure can retrieve a crate. Each figure can carry only 1 crate. A small figure carrying a crate cannot attack.
Crates have 5 Health. When an attack targeting a small figure is declared, that figure may choose for a crate it is carrying to suffer up to 3[Damage]. Then, apply +X[Block] to the results, where X is the [Damage] the crate just suffered.
When a figure carrying a crate enters the extraction point, discard that crate and that figure scores 10 VPs minus 2 VPs for each [Damage] that crate has suffered.
