For you.

For average peasant of early 20th century, who didn't seen any machine in life, even this thing may look threatening.

Until middle-late Soviet times there were common exercise for infantry called something like "tank training", when tanks are moved over soldier laying between tracks. Main goal was to train soldiers to not be afraid of tanks and any other large machinery, because person who didn't seen that thing may be overwhelmed by fear.

Nowadays even peasants from backward places are ok with tractors and harvesters, and city dwellers sometimes don't fear cars even in situation when they need. And modern kids seen much more scarier things on TV and in games.
