I am not sure which units you saw but it is true that today a normal Pakistan Army solider is well equipped and groomed compared to what it used to be some 10 - 12 years ago. I wont compare it to Indian soldier or anyone else as i have not seen them but i can say for Pakistani soldier that the facilities he is provided with in the battlefield have increased. All this happened during the (still on going) war on terror in our northern and North Western areas. The upgrade came more as a necessity rather then proactive approach. One could argue that whether the lessons learned there were transferred to units in Sindh or lower Punjab or elsewhere for that matter. As far as i can tell by my recent experiences of meeting some army men, i would say that yes they have!
Its the level of education of soldiers which has effected the over all outlook of the army since the soldiers now need to have a better education level to handle modern digital electronic weapons systems(especially C4I), so reading, understanding, writing and speaking in english is a must now.I think its either Matric or FA level now
Previously even 5th graders and 8th graders made it into ranks.
In some arms, soldiers were more proficient, like Signals, EME, Engineers, Artillery, Air Defence.
Artillery is mostly about trigonometry.
Air Defence about radars.
Signals about communication sets, cabling etc
EME about mechanical/electrical systems of vehicles
Engineers about civil works, bridge laying etc
For Ordnance, infantry, armour, ASC, RVFC....anything used to go. Infantry being the biggest arm could absorb a large lot of soldiers.
But having ATGM systems, use of infantry locating radars etc in infantry.
IBMS systems in tanks, in Armor
computer database systems in Ordnance
and over all computer literacy, every soldier need to be a well educated individual.
