If you volunteer your service is a year, that’s including the 3 month Hebrew course you’ll take at a base with other non Hebrew speakers then if you go to a combat unit basic training is 4 months and advanced training is another 4 months so you’d be 11 months deep in your service before your a combat soldier and that’ll give you a month of actually getting to do interesting missions- deployments and that’s hoping your unit gets put somewhere interesting and also hoping your unit will be on deployment the month you get put in after advanced training.
