I concur with the above. One thing not mentioned was your genetic makeup which will govern how well/poorly you recover and supercompensate, your age, and other stressors in your life that can have an effect on the amount of umwanted hormones in your system. The three key variables that you will have to monitor are: intensity, frequency, and volume. By training to momentary muscular failure, you are striving for high intensity (few actually reach this and can truly say they went to failure, btw). Thus, to allow for proper recovery and results to show, the other two variables need to be adjusted accordingly. Ie. high intensity = lower volume and less frequency. Training the same muscle groups every day (ie high frequency), while the volume seems to be low (only two exercises) will likely lead to overtraining for said muscles, and perhaps overstress injuries of the supporting tissues and joints.
Keep an exacting log of your exercises, dates, number of sets and reps (or time under tension for even greater accuracy). If you are not progressing every single session (given all variables are in order - the three mentioned above, rest, nutrition, social stressors inlc alcohol etc), then your muscles are not recovering from the previous bout. Exercise is an artificial stressor (we're not hunting for food anymore) imposed on our system to make us faster, stronger or whatever your goal may be. Thus, there is a non-arbitrary purpose behind you spending hours every week working out. The expected results should match this philosophy. Exercise science is a branch of medical science, and should be treated as such. Think scientifically about what your goals are and how to reach those goals, specific to you and your unique genetic makeup.
In sum, you are on the right path thinking of limiting the overall volume to two exercises and going high-intensity (to activate the stress response mechanism). However, check your frequency, as you may find, again depending on your genetics and other variables, that the specific muscle groups may become overtrained quite soon. As your strength goes up, your recovery ability does not generally keep up. Therefore, you need to adjust your frequency. It is not unheard of, for advanced trainees doing HIT lifting very heavy weights to rest for 4-5 days before the next bout.
Finally, think holistically about your expected physical tasks in the military. Limiting your exercise to two basic exercises (two good one at that) only may limit your capabilities as a soldier. Perhaps a routine of 8-12 exercises covering the upper and lower body, focusing on multi-joint exercises every 2-3 days initially (adjusting to the right when you get stronger and the corresponding stress goes up) may balance your conditioning.
Cardio is important and can be done on the "off" days. Again, being a stressor, this will impact you overall recovery ability and has to be factored in when tracking your progress and schedule.
