What was the right to play this?
You should have already stated whether to fire at the WE or the non WE unit (out of LOS should have meant you cannot target the non WE unit anyway).
from 3.2.1
Quote:
If a formation includes both war engines and non-war engine
units then an attacker must state whether any attacks he makes
on the formation will be directed at the war engines or the other
units in the formation. Attacks directed at the war engines can
only be allocated against war engines if they hit, while attacks
directed at other units may not be allocated to the war engines in
the formation
