Several scenes show Bodie's Capri with no rear view mirror.
The mortar Tug is firing when they attack the chemical establishment is effectively hand held so can't be aimed accurately. It's no wonder that Len is killed by one of the rounds.
Note: Lawson foolishly continues the mortar barrage after Len advances forward, and so the friendly fire outcome is rather inevitable (which is the prime reason for Len's death rather than how Lawson holds the weapon). As an experienced soldier, Lawson would know the imperative of halting the bombardment once his own men advanced forward in range of it.
