Nup. There was a fair amount of strategy involved. True, the generic strategy was to line up in a field and blast each other, then engage in bayonet combat with artillery in the early stage and cavalry trying to break enemy ranks, but there were plenty of kings and generals (Frederick the Great, Napoleon, that Dutch guy) who engaged in innovative strategies that involved feints, traps, surprise attacks, et cetera. The Eastern front of WW1 was Germans and Russians throwing gas at each other for the most part, while the Western Front was more of a slugging match then your average pre-Great war battle. The Brits didn't have that many innovative strategies, which is why the French and Native Americans tore them apart during the Seven Years' War.
