It's hard to compare because of the ranks,all benefits soldiers get compared to other countries and above all the cost of life in the compared countries.
In France,a single soldier without children and without rank gets about €1,320 net each months. The salary depends on the situation of the soldier,if he is married or not,has kids or not...
Of course that doesn't include all bonus,benefits and financial advantages the soldiers get. They are also freely housed and fed in barracks. The more you are promoted,the more you'll get obviously.
On average,French soldiers are paid about ~€36.000 gross/year.
