Which, with the chargen waste mechanic, er, death, could be frustrating. Hence, there seem to be a lot of house rules and fudging in this area, not to mention dropping the death mechanic (and later editions provided more skill options, and, in the case of Mongoose, did eliminate standard chargen death). I had no problem with the death mechanic, on principle, but for players who weren't trying to be munchkins, it was a waste of game time.
ALL post-CT editions removed death as the norm. All post CT editions use short-term-and-out except MGT and T20, both of which add mishaps on failure, but don't automatically result in expulsion from service on failed survival.
MT: Short term of 2 years and out. (PM p.14) Death optional.
TNE: no survival throw!
T4: was short term of 1d3 years and out. Death optional.
GT: No prior service system
T20: survival mishap, which can include force-out. No death option.
MGT: mishap & out. (CRB p.8) Death optional.
