Our dear friend Tzvi Sheinkin (the Hero from Hendon) from London writes:
In 1983, I was privileged to serve as a volunteer on an IDF base. Effectively, I was no more than a "toy soldier" (see photo, left), working in the warehouses, checking equipment, cleaning and loading M16 clips and playing a lot of frisbee.
During the two months I was there, I learned a number of things:
1) An army base is no place for a woman - religious or otherwise;
2) How to paint. I'm an expert in black and green - if you ever need anything painted in those colours, then I'm your man!
3) How to shoot. I was taught how to use an M4 (aka short M16) and if you ever feel threatened by empty Coke cans, then do give me a call. I promise they'll never bother you again! (It would have been nice if they had given me some ear plugs: I lost my hearing for 3 days afterwards!!)
One particular incident stands out in my mind. One of the soldiers, Capt. G, was courtmartialed for making a very big mistake. Capt. G was responsible for seeing Armored personnel carriers to the Jordan border. Due to an oversight, he forgot to send the ammunition. What this meant was that for a whole week, the unit was patrolling the border, resplendent in their APCs with their heavy machine guns - but with no bullets!
Let's think about this for a moment.
You have soldiers who have trained hard for months on end. These were men who were totally committed to defending the Jewish People - yet, if G-d forbid, terrorists had appeared, not only would they have been sitting ducks themselves, but the Jews in the settlements were now defenceless too. The training, the guns, the bravery - it would all count for nothing.
Our Rabbis tell us that when we speak loshon hara - slander and evil speech - we ruin our prayers. We render them useless. We might look the part and sound the part, but our words do not reach their target. It's as if we're firing blanks. That means that not only can we not daven for ourselves, but, G-d forbid, when we pour out our hearts for a family member or friend, we're not going to hit the target.
That's why loshon hara is so serious (as is talking during chazaras hashatz or during Torah reading.) Our only weapon is Prayer - so let's not shoot ourselves in the foot!
