Guerra peruano-ecuatoriana
The Peruvian tank battalion played an important role in the 1941 Ecuadorian–Peruvian War, spearheading the attack across the Zarumilla River and at Arenillas. This was helped by the fact that the Ecuadorian Army had no modern anti-tank guns and their artillery was horse-drawn. Ultimately the last LTL tanks would see retirement from active service only in 1988.
