Adventure is a part of the life of someone who is in the defense forces, one of the many aspects of their lives. Keeping other aspects aside for the purpose of this discussion, I would agree with Sun that being in the defense does give you better access to even normal adventure sports such as skydiving, parasailing, river rafting, skiing, etc. etc. Other than that, the constant traveling is also an adventure of sorts, discovering new places, having interesting experiences.
If you want to be surrounded by like minded people who share your love for adventure, physical activity, supreme responsibility and duty, and most importantly, love for country and a wish to serve it, then join the defense forces.
#569147 Balasubramanian, the training is usually either 1 year long or 4 year long before they are commissioned as officers. This is infact the most interesting part of the defense life, friendships formed at this stage last a life time. It is extremely tough true, but people don't get bored at this stage, it doesn't give you any chance to get bored. Exhausted, fatigued, burnt out, maybe... but never bored. Some do give up, which is good that they do it at the training stage itself.
Plus it is usually the younger lot that are actually posted to many of the field posts. If you ever look at the number of MVC, PVC, VC holders, you will find that majority of them are under 30.
#569157 Mr. Rao you contradicted your own statement. You said people join the forces by choice, then by the same logic the adventure that comes along is also by choice. :)
