An Africa watcher noted:
Oil in Mozambique was a forerunner to trouble. I wonder where RENAMO got their new uniforms and arms?
Crowbat's observations are more recent than the IISS Military Balance, which shows the army is 9-10k, with less than 10% of equipment working and one wonders how two attack helicopters will make a difference.

I too recall the FRELIMO-RENAMO conflict many years ago, although I do not have the cited book. Earlier books, from the Rhodesian era refer to the skill of FRELIMO at times in countering incursions. At one point in the period the UK sponsored an infantry battalion to protect the railway IIRC to Malawi.

It will be interesting to see if those RENAMO fighters who did integrate into the national security forces remain loyal - at least Mozambique has better economic prospects, so may be able to retain loyalty by buying it.
