Following the Greek forest fires in 2007, Serbia sent six M-18 Dromader and one Antonov An-2 firefighting planes, 6 firefighting all-terrain vehicles, 55 firefighters, and put specialized military units on alert in case they were needed to assist the Greek Army battling fires and clearing out the debris. According to Assistant Minister of Interior Predrag Maric, over 300 firemen signed up for Greece in less than an hour.
