Is it possible for one to pray with their eyes if they are unable to combine prayers in the military barracks?

The obligatory prayer does not take a long time; it is the pillar of the religion and its strong foundation, and it is the first thing a servant will be questioned about on the Day of Judgment. There is no good in a deed that causes one to miss prayer. Combining two prayers is permitted in situations of difficulty and hardship, but gesturing is not sufficient. Whoever abandons something for the sake of Allah, Allah will compensate him with something better, for Allah Almighty says: "And whoever fears Allah - He will make for him a way out, And will provide for him from where he does not expect."
